Hi Maria!
Thank you for bringing your question to the Disney Parks Moms Panel!
I just love
Disney's Polynesian Village Resort. Not only is it a tropical paradise, but it is also home to my family's favorite restaurant on Walt Disney World property,
'Ohana! In fact, I wish I was there right now!
Normally, the
resort monorails begin running as early as 7 a.m. for Guests to accommodate those with breakfast reservations. It's always a good idea to check with the front desk the night before to confirm the monorail schedule. I would try to leave by 7:00 a.m., to ensure you have plenty of time to get there and get in the park.
I do think the monorail will be your quickest way to travel from your resort to
Magic Kingdom Park for your reservation at Be Our Guest Restaurant. There are also
ferryboats that travel there and make for a very scenic ride. If you don't take them that morning, I suggest taking one at some point during your trip. The views are spectacular!
Once you arrive at the Magic Kingdom, look for a designated line for early morning advance dining reservation Guests. A Cast Member can point you in the right direction if you don't see a sign. That may get you in a little faster than waiting in a normal entry queue.
I hope this helps! Please let me know if you have any other questions.
