Once a friend and I stayed at a Hoiday Inn in Floriday & let (older) kids come & go to the pool, while we sat and sewed. We really did get a lot done & the accomodations were very convenient. I agree about calling ahead and asking for tables/ironing boards & irons/ laundry(so you don't have to use much space for non-quilting things)/.etc.
Have a wonderful time & re-charge your batteries!
