puerto rico: If I am flying frmo the US to puerto rico to hop on a cruise, will I need to go through immigration into puerto rico before I can head to the ship to board? I realize I will need to on the way back, but what about on ther way there? Also, do they make you go through any kind of immigration at each of the stops for the cruise?|||It will be like arriving to any other state. Just get your baggage and leave. Before you go in the cruise you have to go to a line and fill paper work, but again nothing special. You can go to any island you have on your itinerary without going through customs. The cruise company takes care of everything so you don鈥檛 have to. Cruises RULE !!!
