We just returned from our spring break cruise aboard the Adventure of the Seas (AOS). We were on the 7-night Southern Caribbean itinerary that included the following ports: St. Croix, St. Maarten, Antigua, St. Lucia and Barbados. We sailed out of San Juan Puerto Rico. This was our first time in San Juan and our first time at any of these ports of call.
First let me say that we loved the AOS! For us (mom, dad, 15 yr old daughter and 13 yr old son), the size of the ship was great. Not too big, not too small. We are used to smaller ships (Disney ships and Royal's Majesty & Legend of the Seas), so this was a step up size-wise for us.
I have read a lot of negative reviews about Pan American pier in San Juan and their check in process. We had a very pleasant experience. We arrived late (around 3pm) on purpose as we were hiking in El Yunque earlier in the day. I think we waited 30 minutes to check our bags, 15 minutes to get through security and had NO WAIT at all to check in! Crown & Anchor members had a separate line to wait in and we sailed right on through (pardon the pun). Granted, it's not a pretty port (not like Port Canaveral), but it served its purpose. I wasn't there to sight see at the port....
Port side cabin located mid/aft (more aft). Beautiful, unobstructed view. Quiet, easy to access location (not a long walk. Lots of storage space, easily fit all of our clothes and supplies (we over packed slightly). Didn't feel much ship movement, except for the last night when we sailed through a front. Bed was SUPER comfortable, duvet & pillows were SUPER comfortable. Had no problem maintaining room temperature. Great cabin!!
