Hi Vanessa,
Welcome to the Disney Parks Moms Panel!
The self-parking area at
Disney's BoardWalk Villas is a bit of a stroll from the lobby of the Resort. Also, there was a time when the parking lot would get rather full, but that has been reduced to a degree with the roll-out of a new plan that now charges Non-Resort Guests for parking in the Resort parking lot.
If you should decide to opt for Valet Parking, you will want to hold your receipt. Currently, once you pay the valet fee, you may use Valet Parking services at any other Resort for the rest of the day by simply showing proof of payment. Of course, you will still want to pay the gratuity to the fantastic Valet staff whenever you use the service.
I hope that helps, Vanessa. Have a blast on your incredible birthday trip!
Wishing you many magical memories,
Sally
