Am looking at adding a cruise to our january trip (never cruised before). The 3 night cruise would probably fit in better with our plans, but i am wondering if it would be long enough. I noticed on the disney website that they are called 3 night and 4 night cruises, but i am sure it said 3 day and four day on the dreams website. So, is the 3 night cruise only two nights, and is this long enough? Also, on the day of return, what time does the ship arrive back at the port? Thanks.
