Cruise-line private islands have long been a staple of the Caribbean/Bahamas sailing model. Royal Caribbean set a new standard for cruise ship private islands when it overhauled its island and turned it into Perfect Day at CocoCay.

Most large cruise ships sailing out of Florida stop in Nassau, Bahamas. It's a large port with a dock that can support as many as seven ships at a time, and there's no limit to the size of the ships that can stop there.

The US State Dept. has issued a Level 3 Travel Advisory for a very popular cruise port that Royal Caribbean regularly stops at.
