You will have a great time on the Radiance. I am going on her again in Feb 2007. The ruins are great I highly recommend them. As far as geezers go there will be a good mixture of age groups on the ship even in your kids age group. In Montego Bay you really want to visit Dunn's Falls. But do it in a group and try not to venture away to far. Just my advice but I am sure others will agree. IN Georgetown there are beaches to visit and you can actually mail post card and stuff from HELL. In Cozumel if the tour is avaiable I recommend Chichen Itza. It normally books out quick. You can still book tours with RCCL online or with your travel agent. If you wait till you get on the ship you will want to book as soon as your board.
