As the itinerary is now, the Splendor stays in Cabo San Lucas two days and in Puerto Vallarta one day. After taking this cruise in mid-August, my wife and I sincerely feel that Carnival should revise its itinerary and stay two days in Puerto Vallarta and one day in Cabo. In our opinion, Cabo just doesn't offer the range of activities (or the time to enjoy them) that PV does. Whereas PV is a beautiful, clean little town with many interesting areas to visit, I was unimpressed with Cabo, and probably wouldn't have gone back there on the second day even if the seas hadn't been too rough to tender in-and-out of the port.
Other than that one thing, we both enjoyed our trip. The ship was clean, the food was very good, and the crew was exceptional. However, like other Carnival ships with huge atria, getting from one place to another was still a problem, especially when you had to change decks to get there. In addition, excessively-long waits for the elevators made "taking the stairs" a much more frequent activity. I pity those folks who were not as mobile as us.
Even though there is a *lot* of pink used in the interior decor, its possible overuse did not bother us as much as it apparently does others.
One big recommendation is to take the 4-hour "Behind the Fun" tour of the ship on its last day at sea. If you've always wondered how everything comes together on a vessel that size, this tour is for you! And, at the end of it, you get to have your picture taken with the Captain who, incidentally, has just learned that he will become the Captain of Carnival's "Magic" when it begins sailing out of Galveston later this year.
