Which of the following is a main feature of Disney's Polynesian Village Resort?

The main feature of Disney's Polynesian Village Resort is indeed the overwater bungalows. These uniquely designed accommodations offer guests a luxurious stay with stunning views of the Seven Seas Lagoon and easy access to the Magic Kingdom via boat. The overwater bungalows reflect the tropical theme of the resort, providing an immersive experience that captures the essence of Polynesian culture and aesthetics. This distinctive offering sets the resort apart from others at Walt Disney World, highlighting its commitment to providing a premium and enchanting vacation experience.

Other options, while potentially appealing in different resorts, do not pertain to the Polynesian Village Resort. Mountain lodges are typically associated with ski resorts rather than tropical themes. Water slides may be found in other Disney resorts, particularly those with water parks, but they are not a hallmark feature of the Polynesian. Luxury tent camping might be a fun, adventurous choice at other outdoor or safari-themed locations but does not represent the tropical theme and infrastructure present at the Polynesian Village Resort. Thus, the bungalows are a standout attraction, reinforcing the resort's unique character and appeal.
