There is a laid-back vibe on the 3,646-passenger Carnival Dream, where highlights include the pool, the casino, live shows, and movies on the jumbo screen on deck. The ship has 10 restaurants ranging from a 24-hour pizzeria to the Taste Bar, which serves complimentary tapas-style bites of the highlights from menus found in the ship’s other restaurants. (It's a great way to see if you want to splurge on one of those specialty restaurants). One caveat: Carnival may have packed a lot of activities into the ship's 1,000-foot length, but standard cabins aren’t especially large.
