I am currently debating the same thing regarding to hop or not. We are staying at BLT as well, and have 2 kids who will be 6 during our trip. In addition, my parents are coming with us who just turned 70. My kids have never been to Disney, but I always hoped on previous trips (my parents were much younger though). Ideally I enjoy going to one park in the morning, going back to the room to rest/swim and then going back to a park for dinner etc. Good luck with your decision!
