Hello Rebecca!
Welcome to the Disney Parks Moms Panel with a great question!
Since you have a very early dining reservation for Bon Voyage Adventure Breakfast at
Trattoria al Forno, and because there is no direct transportation between Disney’s Polynesian Village Resort and Disney’s BoardWalk, I recommend taking a taxi or a
Minnie van at around 6:50 a.m. or 7:00 a.m. at the latest. This will allow you to travel comfortably, and without having to first go to a theme park and then catch a bus to your final destination. In addition, some routes and types of transportation may not be operating so early, and you need to bear in mind that Guests are advised to arrive around 15 minutes before their reservation time.
After breakfast you can take a water taxi from Disney’s BoardWalk to Disney’s Hollywood Studios! I simply love this ride, and you will get to make quick stops along the way at Disney’s Yacht and Beach Club Resort, and Walt Disney World Swan and Dolphin Resort.
I hope this helps you while planning, Rebecca! Please stop by real soon if you have more questions.
Best magical wishes,
Thiana
