How We Choose Wedding Venues

A 150 guest wedding strikes the perfect balance, large enough for energy and elegance, but small enough to stay personal. You’ll have the joyful buzz of a crowd without losing intimacy. When looking for venues with 150 guest capacity for our clients, here are a few things we look for:

1. Guest flow (no tight aisles or service choke points),
2. On-site ceremony option (if needed)
3. Weather-secure backup location: If any part of the wedding will be outdoors or on a rooftop.
4. Rules and policies: Think load-in rules, elevator and power access, sound, and curfew policies.
5. Accessibility: This include routes for guests using mobility devices, parking, elevators, and accessible restrooms. 
6. Preferred Vendor Requirements, etc. 

Essentially, we look for any restrictions that could affect our design, timeline, or overall guest experience. 

“I worked with Colleen for our wedding and she was so helpful throughout the process. She had good advice coming from years of experience and was always communicative and quick to respond. She made the whole wedding day feel easy and smooth and I am so glad we made the decision to work with her!”

How We Made It Work

We reimagined the space using split seating zones and a custom floor plan that opened up the dance area early in the evening.

• Guests entered through a floral arch designed to frame the river.
• Dinner tables faced the glass façade so everyone had a view.
• We built in 20 extra minutes for sunset portraits, timed perfectly with the boat lights on the river.

When rain clouds rolled in halfway through cocktails, our team didn’t panic. We pivoted. Within ten minutes, our vendors had everything shifted under cover, candles relit, and guests never noticed the change.

That’s what calm, experienced planning looks like.

What to Ask Before Choosing a 150 Guest Wedding Venue

When choosing your wedding venue, it’s important to ask all the right questions before signing the contract. As experienced wedding planners, we often meet clients who booked a venue before hiring us, only to discover the venue does not meet all their requirements. Here are a few questions we recommend asking before signing on the dotted line:

Space and Layout:

• Can the space comfortably fit 150 people with a dance floor, bar, and buffet?
• Is there a flow between the ceremony, the cocktail hour, and the reception?

Catering and Rentals:

• What are the catering minimums and are they realistic for your budget?
• What’s included in the venue rental? (tables, chairs, linens, etc. or will those need to be rented?)

Guest Experience:

• Is there enough restroom access for that guest count? (We recommend at least one (1) per 50 guests for a 4-hour event, and more for longer events). 
• How’s the parking or valet setup for a Saturday night in Washington DC?

Weather Contingencies:

Even the most beautiful outdoor venues, on the sunniest day with no cloud in sight, will need a solid rain backup plan. Crossing your fingers and hoping for no rain doesn’t count.

Planner Tip: Your guest count drives everything: floor plans, catering minimums, and overall flow. Before falling in love with a venue, ensure it fits your real headcount, not your “we’ll keep it small” guest list.
