We cruised on the Magic in June, 2003. The weather was very hot, but the excitement and fun made the humidity much more bearable. As far as the crowds, we sailed in January, 2002, and noticed no difference in the crowds. The pools are always crowded, unless you go early in the morning or after 6:00 PM. The ship is so big, and there is so much to do that you don't notice the crowds. Have a great time!
