Tokelau is always our favorite- it’s closest to Grand Ceremonial House (lobby) and the Oasis pool. But if you’re spending a lot time at Epcot, Pago Pago is a good shout since it’s closest to the TTC, but you run the risk of getting a parking lot view. Moorea is kind of in the middle of those two, it’s also where the Lake View rooms are so if that’s your booking category you’ll mostly likely be in that building. Honestly there’s no bad building IMO, just depends what you prioritize.
