Hi there, Irene!
Thanks for visiting us here at the Disney Parks Moms Panel with your question. I'm more than happy to help!
Depending on how long your dinner lasts, buses from Magic Kingdom may not be running since the park closes at 9:00 p.m. Buses generally operate until one hour after park closing time. However, buses typically operate until 2:00 a.m. between Disney resort hotels and Downtown Disney. So, just hop on a bus to Downtown Disney from
Disney's Contemporary Resort and then transfer to a bus to
Disney's BoardWalk Inn. Hopefully, you'll be able to get back to Magic Kingdom in time to catch the bus from there but if not, at least you'll have another option!
I hope you enjoy dining at
Chef Mickey's as much as I do. It's one of our family's favorites. Be sure to get there early so you can watch
Wishes from the Contemporary's outdoor area.
Wishing you lots of magical memories on your upcoming vacation!
