Welcome, Scott! Thank you for bringing your question to the Disney Parks Moms Panel.
It sounds like you have some great plans in place for your upcoming trip! I love being among the first Guests of the day to step foot on Main Street, U.S.A.
Early Morning Magic and a pre-park opening breakfast reservation will help you begin your day on (literally!) the right foot.
Complimentary resort transportation from
Disney's Polynesian Village Resort to
Magic Kingdom Park is by boat or monorail. For your early morning reservations, I think your best bet will be the monorail. The
Resort Monorail usually begins operations at 7:00 am. The official word on
boat transportation is that it begins approximately 30 minutes prior to park opening. In my experience, operating hours for the boats tend to have some variation, due to weather and other factors. I would check with your Resort Hotel to find out what time the boats are expected to begin operations during your visit. Also, pick up a printed Times Guide upon arrival that will list transportation times.
Another option would be private door-to-door transportation with
Disney's Minnie Van service. Minnie Vans are driven by Disney Cast Members and can be requested and paid for using the Lyft app. Minnie Vans drop off Guests in the front of Magic Kingdom Park in the same area as the buses.
I hope that helps! Please let us know if you have any additional questions. Enjoy your stay!
