Hello Betty,
Thanks for stopping by the Disney Parks Moms Panel. I am sure you are looking forward to your very first Walt Disney World vacation. Disney's Polynesian Village Resort is a lovely location with its island feel and convenience to Magic Kingdom via the monorail. My family has enjoyed our past stays there.
I have several recommendations on where to request your room. The first is the Samoa building. This is adjacent to both
pool areas, the Lava Pool (main) and Oasis Pool, as well as, the Kiki Tiki kids splash area. However, because of this, it could prove to be noisier than other buildings. The Niue building is closer to the Great Ceremonial Hall, the main building with dining, front desk, and
resort transportation. It is also a very short distance from either pool. But, this building could be a tad less noisy. Keep in mind, though that noise levels could vary for a variety of reasons, including high foot traffic times of day such as park opening and closing. The cast members will do their best to accommodate your requests, but they cannot be guaranteed and are based on availability upon arrival.
I do hope this helps you in your planning process. Please do not hesitate to come back with more questions as your trip draws closer. We would love to help.
Have a wonderful vacation!
