Before You Book

Hosts usually book event venues and banquet halls 3–6 months ahead (6–12 for big Saturday events). Ask:

• Is our date available, and how long will you hold it before a deposit?
• What is the all-in price for our guest count, including service charge, tax and gratuity?
• What is the capacity seated, standing and with a dance floor?
• How many hours are included, including setup and cleanup time?
• Must we use your caterer or bar? Is there a fee for outside food, a cake or alcohol?

Booking Tips

• Ask for a sample invoice for your exact guest count; service charges and tax can add 20–30%.
• Fridays, Sundays and weekday daytime slots are often cheaper than Saturday nights.
• Visit at the same time of day as your event to judge light, parking and noise.
