Hello Holly and thanks for bringing such a great question to the Disney Parks Moms Panel.
My family just loves exploring every corner of Walt Disney World Resort via all the many different and delicious dining spots and I'm happy to share that in my own experience Guests with a confirmed Advanced Dining Reservation at any Disney Resort hotel dining location are at present permitted parking in that Resorts parking lot; however it's always worth bearing in mind that during extra busy periods priority parking could be limited to resident Guests of that particular Resort.
Upon arrival to the
Disney's BoardWalk Inn security gate please be ready to provide a valid form of ID, plus your
Trattoria al Forno Advanced Dining Reservation confirmation number which generally speaking should permit parking of your vehicle for up to a maximum of approximately 3 hours whilst you enjoy dining in true rustic Italian style!
Additionally I thought you may also find this
Parking at Walt Disney World Resort to be a useful planning resource for your upcoming magical visit.
Wishing you a magical upcoming visit to Walt Disney World Resort.
