I will try to help you with some of your questions, meeting people at dinner, around the pool and in the bars is usually pretty easy on Carnival. I think the ports you are visiting are very easy to get around, San Juan's port is very close to stores, casinos, the fort, and some bars, St Thomas and St Maarten are just beautiful and very easy to catch a taxi to the beach or shopping. I'm not sure about the cost of ironing, but I take a bottle of Downey wrinkle reducer and with the humidity in the room it works very well. I have gotten an upgrade twice from Carnival so who knows. I have never cruised on Easter before, but I believe they do usually offer a Sunday service (not positive about this). I hope some of this helps, have fun.
