Definitely the Poly, MK fireworks viewing from the beach is a bonus, and it’s on the monorail line so you can easily visit the other monorail resorts for dining, etc. It isn’t the quietest resort because it is so popular with families, but we love the energy of the resort. Also, you can just take a quick boat ride or monorail to Magic Kingdom and take a resort bus to any of the other resorts, such as Riviera, etc, for more dining and resort hopping options.
