While I haven't done your itinerary, I am Platinum on RCCL and they are, as oldpenny says, consistent and a good line to sail with. As far as tours go, after our first cruise 25 years ago, we learned early on never to book with the cruiseline. As a rule, there are always independent offers when you disembark off the ship and you should not have trouble finding things to do that way. It will be much cheaper.
