I am the Royal Caribbean QUEEN. Love them!
While all their ships are beautiful, I especially recommend the Voyager Class of ship. It's absolutely the best laid out ship sailing today. (in my opinion) There's so much to do and the kids will thank you for it. Their kids program, Adventure Ocean, is awesome. Plus for older kids there's a teen Disco.
We love Explorer of the Seas...check it out! And by the way, I'm just a nut about Royal Caribbean...I don't work there or anything!
