Hello there, Madeline!
This sounds like my type of trip!
Beaches & Cream Soda Shop is one of my favorites. The last time I went there, I tried my husband's Impossible Burger with the Caramelized Balsamic-Onion Jam, which was out of this world. I suggest topping your dinner with the Kitchen Sink (serves four) sundae. This will be the perfect sweet treat to give your group a sugar kick before you start singing "Part of Your World" at
Jellyrolls.
I recommend parking at
Disney's Beach Club Resort since this is where you'll find Beaches & Cream Soda Shop. Disney's Beach Club Resort is a short five to ten-minute walk away from Jellyrolls. Either way, I spoke with a friendly Cast Member, and they said you should be able to park at either Disney's Beach Club Resort or Disney's BoardWalk Inn with your dinner reservation for about 3 hours or so. Make sure to have your party's name or reservation handy in your My Disney Experience app in case the parking attendant needs any information to confirm your dining reservation.
My family has been taking vacations around Disney's Boardwalk for years! I love the convenience of taking a Friendship Boat or walking to EPCOT's International Gateway or Disney's Hollywood Studios entrance. Besides Jellyrolls, your group may have fun playing classic arcade games along the boardwalk or renting out a Surrey bike built for four.
Let me know if you need anything else.
May the magic be with you!
Melanie
