Blogger David Molyneaux has listed the Regal Princess as one of his favorites:
Best onboard place for people watching
International Café on Regal Princess (and Royal Princess), new out of Fort Lauderdale.
Grab a latte ($2.50), day or night, a complimentary snack such as a panini, individual pecan pie, or chocolate mousse. The café is in the Princess Piazza, which sits grandly at the heart of an elegant three-deck atrium done up in marble, with sparkling light fixtures, staircases, theatrical balconies, and water fountains.
The Piazza is the hub of the ship, a place to hang out for hours and be entertained by the parade of passengers as well as scheduled entertainment such as a pianist or string quartet.
