Hey Howdy Hey Kristina and welcome to planDisney!
You are in for a real treat on your upcoming stay at the Walt Disney World Resort.
Disney's Polynesian Village Resort is a great choice for hotel selections. This resort has the relaxing comforts of the islands as well as all the conveniences and access to the Magic only a Disney resort can offer. One minor thing is the lack of available gym options onsite! Thank you for your question on gym access. I will be happy to give you more information.
Kristina, it is my understanding that you are correct, at this time, Guests staying at the Polynesian resort will have access to the gym facilities at
Disney's Grand Floridian Resort and Spa. As policies do change, I would make sure you check with the front desk on your arrival date just to be sure this is still the case. I would also double-check to make sure the walkway from the Polynesian and the Grand Floridian is open. As construction is winding down, you should not have any issues however from time to time this may change depending on projects that are being completed.
If you are a runner or enjoy a walk with fantastic views, you would have an option to travel from the Polynesian resort to Magic Kingdom. This run/walk is a great way to get your day started and enjoy the sun rising along Seven Seas Lagoon. It is super peaceful and a beautiful path to navigate the resorts.
I wish for an amazing vacation for you on your upcoming trip, one that is full of Magical memories. If you have any other questions let us know, we are always happy to help!
To Infinity and Beyond,
Nick
