We stayed at Hilton Bonnet Creek last summer (never been to Hilton Orlando). We would stay there again in a heartbeat! We also said that the hotel is a destination itself (i.e. no need to go to the parks while you are there). The pool is HUGE - zero entry area, big lazy river, kiddie splash pool, waterslide, etc. Also, the pool bar/restaurant is very good, kids eat free at breakfast and dinner in one of the restaurants (breakfast=good, dinner for adults=ok). La Luce (nice restaurant on property) was the best dinner we had all week! Fabulous food and they treated our kids wonderfully. Plus, you have full access to all of the Waldorf facilities too, including the golf course.
I highly recommend it.
