When you're renting a location, there are certain question you must always ask.
Do you provide items like tables, chairs, glassware, or linen, and is the cost included in the rental price? A location providing these items is a big plus! Rentals can be very costly, especially when you tack on roundtrip delivery.
What facilities will I have access to? You want to make sure that there are safe, clean restrooms nearby, and a working kitchen if necessary.
How late can I play amplified music? Many public places have a noise ordinance that might cramp your plans for an all-nighter.
Is there an extra charge for the use of your air conditioner or heat? A few years ago, I was installing the decor for an event at a popular historic location in Los Angeles. When the temperature reached 100 degrees, we inquired about the air conditioner, only to find that it was an extra $400 for 4 hours.
What about parking? Many public places don't offer parking, and the additional cost can be steep.
Are there any activities, beyond the obvious, that are not allowed or would require a special permit? Most locations do not allow candles or alcohol consumption without a special permit. More notably, some older locations will not allow dancing on their newly restored floor!
Do you have any photos of previous events? Any photos of events around the same time as my party? It's great to see the location brought to life by an actual party. Not only will you get ideas for event set-up and decor, you can avoid any pitfalls like putting the buffet table in direct sunlight.
Can you recommend any vendors? The location may have special rates with certain vendors, and the vendor might have some pointers the site.
May I have a list of references? It's always smart to check references, and make sure that most people had a good experience with the location and personnel.
Is there anything I haven't thought of to ask, or any other advice you can offer?
