Hi, my name is Riana, and my boyfriend and I have begun planning our first cruise. We plan to go sometime in Sept. So far all we have seen are Carnival cruises, we want to deport from a city that is within driving distance (we are in dallas texas), but I noticed a Princess cruise leaving from Houston. How do these two compare? What are the differences? We have only looked at Carnivals ships and ports, we had 'decided' on the Conquest deporting from New Orleans, but then I saw this Princess and I hear it has a movie theatre and that sounded romantic. Please help thank you!
