Fiji handles 300 delegates comfortably in plenary — at least four properties publish a room that seats 300 or more — and the constraint that actually bites is concurrent breakout rooms. If your programme runs three streams of 100, the shortlist drops from four venues to three. Plan the breakouts first and the plenary will look after itself.

Which Fiji venues genuinely qualify at 300?

These are published figures from each resort's own site. A venue "qualifies" here if it publishes a plenary space at 300 theatre or more and can seat 300 at banquet for the gala.

InterContinental Fiji Golf Resort & SpaWatercourt Conference Centre ballroomup to 600not publishedPlenary yes; banquet unconfirmed
Fiji Marriott Resort Momi BayGrand Salon Ballroom400250 or 300Marginal — the resort's own figures conflict

Two honest notes. Marriott Momi Bay's page describes the Grand Salon as seating up to 250 banquet while its own chart says 300, so at a 300-person gala you would be negotiating against an unclear baseline. And the InterContinental publishes only "seats up to 600" for the Watercourt — no banquet, cocktail or classroom figures and no floor area — so the plenary is confirmed and the gala is not.

Other properties may well do 300. The Westin Denarau Island Resort & Spa and the Warwick and Outrigger properties ON the Coral Coast are all worth briefing, but they do not publish comparable capacity charts, so we are not going to assign them numbers.

What is the constraint that bites first?

Breakouts. Almost every 300-delegate programme splits into concurrent streams at some point on day two, and a venue that seats 300 in plenary does not necessarily have three rooms that seat 100 each.

Here is the same shortlist measured against three concurrent streams of 100, theatre-style, on published figures:

VenuePublished rooms that seat 100+ theatreThree streams of 100?
Sheraton FijiBallroom A 280, Ballroom B 130, Ballroom C 130 (plus Golden Ballroom 600)Yes — comfortably
Shangri-La Yanuca IslandRatu Makutu I 300, Ratu Makutu II 300, Davui Hall A 180, Davui Hall B 180Yes — comfortably
InterContinental FijiThree theatre-style rooms at 110 each, each divisible into twoYes — exactly, with no spare
Marriott Momi BaySalons 1–3 at 70, 80 and 70 banquet; Island Board Room 70 theatreNo

That table is the real shortlist. The InterContinental's three rooms at 110 are a precise fit for a three-stream programme and leave you nothing if a stream over-subscribes — which is a manageable risk if you pre-register streams and a serious one if you do not.

At Marriott Momi Bay a three-stream day would mean running one stream in the plenary room and re-setting, which is a crew cost and a changeover window rather than an impossibility. Price it before you rule it out.

How much room inventory does 300 delegates need?

Assumption, stated plainly: 300 delegates at 1.25 delegates per room is 240 rooms. That ratio assumes a largely single-occupancy corporate group with some twin-share and some partners. A heavily partnered incentive-style group runs closer to 1.8 per room and needs around 170; an all-single-occupancy government group needs 300.

Use your own ratio. The number that matters is not 240, it is your 240, and getting it wrong by 15% is the difference between a comfortable block and a multi-property scramble.

Two structural points about Fiji specifically:

  • ON Denarau Island, 240 rooms across one or two properties is achievable, because the precinct holds several large resorts within a short walk or shuttle of each other. That is the whole reason Denarau is the default for events over 250.
  • On a single island resort IN the Mamanucas, 240 rooms is not achievable. Island properties are small. A 300-delegate conference IN the Mamanucas is a multi-property event with boat movements, which is a different and much harder programme.

If you end up across more than one hotel, read multi-property conferences: running one event across four hotels and how room blocks work in Fiji before you sign anything.

How do you move 300 people from the airport?

In waves, matched to arriving flights rather than to a schedule you invented.

The method: list every inbound flight with its scheduled arrival, group delegates by flight, and build one coach wave per arrival cluster with 45 to 60 minutes of clearance slack after each scheduled landing. A group clears immigration and customs more slowly than individual travellers, and a second widebody landing in the same window will slow you further.

We are not going to publish coach seat counts, because operators' fleets differ and the number you need is the one in your quote. Coach charter in Fiji: fleet capacity and cost has the operator picture, and how do you move 300 delegates from Nadi airport works through the wave structure in detail.

One piece of arithmetic that always surprises people: if your delegates arrive on four different flights across a nine-hour span, you are running airport meet-and-greet for nine hours, not for one. Staff it accordingly — see airport meet and greet for conference groups.

For the lift itself, start at Fiji air access for planners. As a sense of scale on a single origin: Brisbane–Nadi runs on a mix of 737 and widebody equipment depending on the day, so 300 delegates out of one Australian city will almost always span multiple departures.

What does catering at 300 actually require?

Three things that are easy to miss and expensive to discover late.

Banquet kitchen throughput. A ballroom rated at 300 banquet does not guarantee a kitchen that can plate 300 covers in one service. This is the most commonly unchecked constraint in Fiji and it has its own article: banquet kitchen capacity: the constraint nobody checks.

Break service footprint. Three hundred people need a pre-function area that can absorb them in a 20-minute break without a queue. Sheraton publishes a Pre-Function capability and Shangri-La publishes North and South pre-function areas at 140 and 340 reception — that South figure is the kind of number worth checking at your shortlisted venue, because a 300-delegate break in a 140-person foyer is a bottleneck.

Dietary volume. At 300 delegates you will have a meaningful count of vegetarian, vegan, gluten-free and halal requirements, which is a kitchen planning question rather than a menu question. Dietary, halal, kosher and allergy handling at Fiji events covers what Fiji does easily and what it does not.

What about AV and production?

At 300 in a wide room you need screen coverage for the back third, delay speakers, and enough radio microphone channels for a panel plus floor mics. In-country capability exists — Encore Event Technologies Fiji operates ON Denarau Island — and specialist inventory for a larger show is often flown in, which brings customs into scope.

Start with AV and production in Fiji: what's available in country and LED walls, projection and screens.

What should the budget look like?

We publish per-delegate costs separately and keep them in one place rather than restating figures that move. Build the budget from what a Fiji conference costs per delegate and the Fiji conference budget template, then pressure-test it against where Fiji conference budgets blow out.

At 300 delegates, the three lines that move most are airfares, ground transport waves, and the gala. The venue hire is rarely the problem.

The worked recommendation

If your programme is plenary-heavy with two streams: any of the four venues above works, and you should choose on transfer time, accommodation fit and rate rather than on capacity.

If your programme runs three or more concurrent streams: Sheraton Fiji or Shangri-La Yanuca Island, both of which publish genuine spare breakout capacity. The InterContinental fits exactly and is excellent if you pre-register streams.

If the gala is the centrepiece: Sheraton Fiji, which publishes 1,000 banquet indoors plus outdoor options at 500 and 800 banquet, giving you a wet-weather decision that does not shrink the event.

If you want one resort, one island, no shuttles: Shangri-La Yanuca Island, where the whole event sits on one property.

Next step: compare the published numbers yourself on the capacity charts, look at the step down in the 200-delegate plan, and brief two venues against identical requirements using the Fiji conference RFP template.
