Hello again, it just appeared to me that I forgot to answer your question. Yes the Crown and Carribean are very similar. I have sailed on the Carribean and it is impressive one of the biggest ships in the world and lots and lots of things to do. The Crown is newer and bigger. It also has a Piazza style plaza with nice little eateries and shops.
I hope this info helps. I can also tell from your tickler that we are both on the same cruise. I really hope you can help me with my request from my first email.
