here's something you may want to investigate, cause I know how'd I'd be foreced to react...
If you have entry fees, you'd need insurance and an OK from the resort.  otherwise, you'd more or less recieve no help what so ever, and may actaully get the boot.   Liability insurance is the killer of all good times, but as a neccessary evil, you may want to think of ways to work in the confines of responsible adults.   Try your sponsors to see if they can help...
or just go for it, cause it sounds like it;d be fun.
