All in all we booked this cruise one week before we left and it was well worth it. The Royal Caribbean cruise was a 7 day Southern Caribbean cruise out of San Juan, visiting: Aruba, Curacao, St. Maarten, and St. Thomas. We paid roughly 750 per person, and thought it was a good deal.
We arrived in San Juan the same day as our cruise at 4am. The cruise left at 8:30pm later that day and we had planned on just touring through San Juan. However after the long flight we thought it was best just to check into a hotel ASAP as we were very tired. Since we hadn't booked anything we asked a cab driver where we should go and he recommended a couple of hotels for 200+. I didn't believe them and just went to the airport/casino hotel and booked a great room for 120$! The room was very clean, free internet, a great free continental breakfast, and no TAXI ride. I definitely recommend this hotel.
Later that day we woke up and shimmied over to the ship. It is a dandy... very big at 130k cubic tons. We were very please with our Cabin on the 3rd Level, and started exploring the ship.
