We just returned from a land/sea package -- 3 days land and 4 days sea. I just want to mention that with the 4 day cruise, our land was still first. Our package went from Thursday to Thursday, rather than Sunday to Sunday.
I liked the idea of doing the land first and then the cruise, but didn't like the Thursday to Thursday at first. However going back to work on Friday wasn't as bad as I thought since I knew it was just that day and then the weekend! And then Monday wasn't even as bad since I had done some of the catching up on Friday.
