Lori,
We stayed at the GF in October in a suite and had access to the RPC; my DH and I stayed in the main building a couple of weeks ago and used the RPC lounge then as well. We absolutely loved it and thought it was perfect for our needs. In October, we were with our 2 kids, my 75-year-old parents and my sister and niece. We used the lounge every morning because we are a family who eats cereal, toast, bagels, fresh fruit, yogurt, etc. for breakfast. We did not use the lounge in the afternoon except on ourr arrival day and we had scones, cookies, sodas, etc. The evening offerings were plentiful and varied and we loved the desserts/cordials. My kids could hardly wait for the chocolate covered strawberries! After our stay in December, DH said. "Why stay anywhere else?" We really loved the atmosphere and understated elegance of the RPC. But honestly, I'd be happy to be in any room at the GF!
DS and I will be back there in Feb. but in a garden view room (great AP discount!) and we will probably use room service and Gasparilla Grill. Even eating at poolside is great at the Grand! Good luck with your decision - let us know!
