This was our third Princess cruise and I would say it was the least favorite of our three cruises. The ship is very nice but I don't think they needed to add an additional deck since 3,100 people is a little excessive. The Grand and Golden hold (I think) about 2,600 and they never felt crowded.
Embarkation: We arrived in Ft. Lauderdale and we were immediately met by a Princess representative. They transported us to the ship and the boarding process went for the most part without issue. The only issue was that they had "mis-filed" our cruise cards. Since this was our third cruise with Princess, we should have received Gold cards but do to the "mis-filing" we were given the basic card. Not a big deal for us but a short coming on Princess' part.
The Cruise: The weather was fantastic the entire week which is very lucky considering the time of year. Princess Cays was very nice but it was the first place we started to the notice the amount of people. Montego Bay was the only port where we did an excursion and it was very enjoyable. We did the River Tubing and my 12 year old son had a great time. Grand Cayman and Cozumel were both very nice but all we did in these ports was shop. Since this was our third visit to the Western Caribbean (2 on Princess, 1 on Carnival), we didn't swim with the Sting Rays in Grand Cayman but it should be done if you have never done it before.
