Hi Nicole, and welcome back to planDisney!
I am so sorry to hear that you are having knee surgery, and I can certainly relate that the aftermath is no fun. A Walt Disney World Resort vacation can undoubtedly make it bearable! If you ask me,
Trader Sam's Grog Grotto is a "must-do" activity, and you will love it.
To enjoy some time at Trader Sam's Grog Grotto at
Disney's Polynesian Village Resort, just let the gate attendant know what you are there for, and they will let you know how you can proceed.
Because parking is available for a limited time for non-guests of Disney's Polynesian Village Resort, I recommend parking at Disney Springs and hopping on the available
bus transportation to the resort to partake in some sushi, a specialty cocktail, or anything else on the menu. Once you are done, hop back on the bus to Disney Springs and enjoy your dinner. Another option would be for you to park at the Disney's Transportation & Ticket Center parking lot and board the
Disney Monorail Transportation to Disney's Polynesian Village Resort. I hope this helps.
Please let us know if you have additional questions; we are here to help.
Have a magical time!
Raquel
