We have done room at Hyatt (1st cruise) which was great when kids were younger and napped. We all swam, napped and watched a movie. Since then, we have done Orlando science center which was pretty good with school aged kids. Our favorite is Kennedy space center. We got their prior to opening and stayed until 3:30 and still got back, dropped off rental, through security with two hours to spare before our 7:30 pm flight last year. We will probably go back to KSC this year post cruise. There is so much to see and do if u are at all interested in space exploration. We were not sure we would enjoy it (having been Johnson space center in Houston) but we al loved it!
