Hi Tiara, Thank you for reading. If I had to compare the Alaska versus the Western Caribbean it would be hard because they were both amazing, but I'd say the main difference for me would be that the Alaska trip felt more relaxing than the Caribbean. It could have been that there was one more day at sea or it may have been because we had been on the Wonder before and already knew the ship. On the Fantasy everything was new, and the ship is bigger, so it felt like we were constantly on the go trying to see and do everything. You can't go wrong with Disney no matter where you decide to go. Have fun!
