Ok thats the vibe I was getting. I don't have time to organize the food, drinks, grills, cooks, etc. If we choose Volo I'll be glad to help out though. I was poking around on the Volo website. They allow tents, and grilling. Here is some more info from the website.
ADDITIONAL OPTIONS FOR ALL PARKS
Groups are welcome to set up tents, tables, chairs, and catering for their events. Rental of port-a-potties is required for any group of more than 50 people. You may bring your own food and may bring grills (gas only). No alcohol or pets allowed in the Volo Auto Museum parks. All functions must conclude by 4:30 p.m. Parks close at 5 p.m.
