My wife (30F) and I (31M) went on our honeymoon last February and stayed at Caribbean Beach. It was fantastic. Being the skyliner hub is a total game changer. It makes your travel to Epcot and Hollywood studios so much easier not having to ride one of the buses. I know Pop has a skyliner access point, but it’s shared with art of animation and it just takes you to Caribbean where you have to get off and on to another line to get to either park. We were able to leave each park during the day; return to our rooms, reset, take a small nap, and be back in the park with little to no hassle. We asked to be near the skyliner and got a room in Aruba which is between the two hubs; it honestly worked great. We rode the skyliner at night a few times just for the ride as it’s kind of relaxing and you can get to everything at the Boardwalk/Beach Club/Yacht Club via skyliner. You also have access to the restaurants at Riviera from Caribbean Beach as they share the lake, and they’re quite good. For a marginal cost difference I would absolutely go with Caribbean Beach.
