Hi Karalyn!
Welcome to
planDisney!
I see that you are visiting Walt Disney World in June, which is just around the corner! Dining at Walt Disney World is one of my favorite experiences! I particularly love
Disney's Boardwalk area! I enjoy viewing the beautiful lake, walking around the boardwalk, and dining at
Flying Fish!
To answer your question, the absolute best way to get from
Disney's Polynesian Resort to Disney's Boardwalk area is by driving. If you will not have a vehicle with you, I suggest using a ride service, such as a cab or Lyft. Since you have a reservation, you will be allowed to park at Disney's Boardwalk area.
Disney's Polynesian Resort is along the
monorail line for
Disney's Magic Kingdom and
EPCOT and you can take
complimentary bus transportation to all of the
Walt Disney World Theme Parks and
Disney Springs. If the reservation was later in the day, I would suggest taking the monorail to the Tickets and Transportation Center (TTC) and then hopping on a bus to Disney's Boardwalk Inn,
Beach Club, or Yacht Club Resorts. However, given that your reservation is at 7:30 a.m. I am concerned that the bus will not be transporting Guests from TTC to Disney's Boardwalk Inn that early. The buses typically begin running from the resorts to the parks one hour prior to the park opening. As such, I am not confident that a bus will be running that early.
I hope you have a magical vacation!
Magically,
Stacy
