You can also take a boat from the Polynesian to the Magic Kingdom. After the Christmas Party, we opted to take the boat back since the monorail was crazy busy. The boat was quick and efficient and it was fun heading back to the resort across the Seven Seas Lagoon.
For access to Hollywood Studios and Animal Kingdom, the Polynesian shares bus service with the Grand Floridan Resort. We had no issues with bus transport during our stay.
Outside of transportation, the Polynesian offers great views of the Electric Water Pagent and the Magic Kingdom fireworks. With its strategic location on the Seven Seas Lagoon, there are plenty of spots along the beach to find a spot and watch the parade or fireworks. Since we were Club Level guests, we watched inside the lounge but saw plenty of open beach space in front of the building.
