After a Princess cruise to the Panama Canal on Coral Princess, we had wanted to do another Princess cruise. The Regal Princess was doing the Baltic and then repositioning to North America. We really liked the variety of ports and wanted to do a Trans-Atlantic. We were not disappointed on either itinerary.
The Regal Princess is an incredible ship and it offers much in terms of comfort, dining and activities.
What was not good about it? The ship is very large and there are steps (or the nautical, ladders) at forward and aft that go to all levels. The amidship ladder is a bit awkward with the intent being that one use the staircases in the atrium. Generally, that works. We got used to it. It would also be nice to have a bar or lounge on one of the higher decks. The Regal Princess, like most cruise ships, looks for ways to maximize onboard spending. They have made the forward, open deck area into what is called The Sanctuary. This is a nice area that they charge for use of. I wasn't crazy about this but as the temperatures were in the 50's and 60's (F) for most of the trip, it wasn't really an issue.
Our cabin - Caribe 740 - was unique for us. It faced aft. That has it's pros and a con. It is really neat. You can see port and starboard and it is very nice to sit on the balcony and watch the ship's wake. But - even on a ship of it's size and technology - we felt more movement at this location (of course). When we left Cobh, Ireland, enroute to Boston, the seas were a bit rough for a couple of days. Our steward - Mark - was excellent. I was amazed at his ability to keep our room refreshed 2-3 times a day with 12 cabins to take care of. He always had a smile and a cheery disposition.
