We stayed there for one night before our cruise last year and paid $79 for a studio. The room was small and a bit cramped, but very clean since the resort was new. The pool area was very big, and the indoor playground is a bonus (except it closed early) especially if it rains. We were very happy with the resort and wished that we had more time to spend there.. especially at that rate. However, when we tried to rebook for this year, the same room was $279. We did not think it was worth it... the resort wasn't "that" nice. And since my MIL was traveling with us this time, we would have needed two studios or a one bedroom (I forget the price that I was quoted but I remember it being very high). (We booked a double King suite at the Radisson for $159...which included a full hot buffet breakfast...My kids had just as much fun in their pool.) My advise would be to check the prices of the other hotels and determine how much time you are planning to stay at the resort. If you are only going for one day... do you really have enough time to use the indoor playground, the mini-golf, the pool (remembering that they close early)? If not, why spend the money (again, it also depends on your rate)? You may be just as happy with a lower rate at another hotel with a nice pool. On a side note, my husband and I found the Ron Jon resort, although their amenities nice, to be very stark and sterile in appearance. It lacks the presentation that the Disney resorts have... a resort theme, beautiful flowers etc...
Have a great time on your cruise!
