Hi Jessica,
Thank you so much for visiting the Disney Parks Moms Panel with your question. I love Disney's BoardWalk Villas. It is my home resort with Disney Vacation Club. I love the hustle and bustle of Disney's BoardWalk. There is so much to do in this area!
The pools at Disney Vacation Club resorts are for the exclusive use of Disney Vacation Club members and their guests who are staying at the resorts. Therefore, by this rule, if your father is not a resort guest listed on your reservation and staying in your villa with you, he will not be allowed to use the pool. I spoke with a cast member at Disney Vacation Club Member Services who confirmed that this is the rule; however, she did suggest that you ask a cast member about it when you are at the resort to see if there is any help they can give you in this regard, but please do plan on your father not being able to use the pool.
Although your father will not be able to use the pool, the good news is that you are in a great location with so much to do right in walking distance! Along
Disney's BoardWalk, you could rent a surrey bike big enough for multiple guests to pedal around Crescent Lake, or you could play in the arcade at The Yard at the ESPN Club. You can walk to Disney's Yacht and Beach Club Resorts, where you could rent watercraft from the marina. There are so many dining experiences available, from the upscale Flying Fish Cafe on Disney's BoardWalk to the classic and fun Beaches & Cream Soda Shop at Disney's Beach Club Resort. I am sure that you will be able to find many fun activities for the day your father comes to visit.
I hope that these thoughts are helpful for you, Jessica. Have a wonderful time planning your vacation, and please do let us know if you have any further questions.
