TL;DR: A 100-guest wedding in Las Vegas typically costs $32,000 – $58,000, with most couples landing near $42,000 when they book a Strip-adjacent or off-Strip venue with full-service catering. Expect roughly 40% of your budget to go to venue and catering, and plan around triple-digit summer heat that pushes most weddings to October–April.
Useful summary
For 100 guests in Las Vegas, the per-guest math lands between $320 and $580, depending on whether you choose a chapel-plus-restaurant package, a hotel ballroom on the Strip, or a desert resort like Red Rock or Lake Las Vegas. The biggest swing factors are venue type (chapel package vs. full ballroom buyout), bar package (beer/wine vs. premium open bar), and season (peak fall/spring vs. July–August).
Las Vegas has a real cost advantage on officiants, photography, and entertainment — the city has a deep vendor bench from the entertainment industry — but loses that advantage on floral and ballroom F&B minimums, which are comparable to or higher than Los Angeles.
Variable data table
Here's how a realistic $42,000 budget for 100 guests breaks down in Las Vegas:
| Category | Typical range | % of budget |
|---|---|---|
| Venue (rental + ceremony fee) | $5,500 – $12,000 | 18% |

Local context
Where people actually get married in Vegas (with 100 guests):
- The Strip resorts (Bellagio, Wynn, Aria, Caesars): ballrooms with $150–$250/person F&B minimums, premium service, no transport hassle. Highest end of the range.
- Off-Strip resorts (Red Rock, Green Valley Ranch, JW Marriott Summerlin, Lake Las Vegas): resort feel, lower F&B minimums ($110–$170/person), often the best value for 100 guests.
- Downtown / Arts District (Smith Center, Neon Museum, Mob Museum): non-traditional venues, $8,000–$18,000 site fee plus outside catering.
- Desert and outdoor venues (Spring Mountain Ranch, Valley of Fire-adjacent properties): cheaper rental but you're building infrastructure (tents, restrooms, generators) — often a wash.
Climate matters more than you'd think. May through September regularly hits 100°F+, which rules out daytime outdoor ceremonies and adds tent cooling costs ($1,500–$4,000) for outdoor receptions. October, November, March, and April are peak season; book 9–14 months out. January and December weekdays are the deepest discounts — sometimes 25–35% off Saturday pricing.
Travel is part of your budget conversation. Roughly 60–80% of Vegas guest lists are out-of-town, so you'll likely cover welcome bags, a hosted welcome event, and possibly shuttles between hotels. Budget $1,500–$3,500 for guest hospitality on top of the table above.

FAQ
What's the average cost of a 100-person wedding in Las Vegas?
Most couples spend $32,000–$58,000 for 100 guests in Las Vegas, with the median around $42,000. The biggest variable is venue type — a Strip resort ballroom typically runs $15,000–$25,000 more than an off-Strip restaurant or desert venue for the same guest count.
How much should I budget per guest in Las Vegas?
Plan for $320–$580 per guest all-in. F&B alone (food, bar, tax, and 22% service) usually lands at $180–$280 per person at a full-service venue, and the rest covers photography, flowers, music, and attire that don't scale linearly with headcount.
Are weekday weddings really cheaper in Vegas?
Yes — meaningfully. Sunday through Thursday weddings often save 15–30% on venue and F&B minimums, and Vegas guests are more willing than average to travel mid-week because they're already planning a longer trip. Tuesday and Wednesday are the cheapest days.
Do I need to budget for guest transportation between hotels?
Usually yes. If your venue is more than walking distance from your hotel block, plan $800–$2,000 for shuttles or a partial Uber/Lyft credit code. Strip-to-Strip is walkable in theory but brutal in heels and August heat.
What's the cheapest realistic option for 100 guests in Vegas?
A weekday afternoon ceremony at a chapel ($1,500–$3,500) followed by a private dining room dinner at an off-Strip restaurant ($120–$160 per person all-in) can land you around $22,000–$28,000 total with simple flowers and a DJ. That's the practical floor for a real seated reception.
How far in advance should I book a Vegas venue for 100 guests?
9–14 months for peak season (October, November, March, April) and Saturdays year-round. Strip resort ballrooms for 100+ often book 12–18 months out for fall dates. Off-peak weekdays can sometimes be booked 4–6 months out.
Does Las Vegas charge sales tax on wedding services?
Clark County applies 8.375% sales tax on food, beverage, and tangible goods, and most venues add a 20–24% service charge on top of F&B subtotals. Always ask vendors for an "all-in" quote — the difference between subtotal and total can be $4,000–$7,000 on a 100-guest reception.
