Hi, Tricia! I know when my kids get off an airplane, they are starving! High altitudes must bring on hunger! If you decide to eat at the airport before heading to Wilderness Lodge, they have a huge food court with many fast food options. There are also some sit-down locations scattered throughout the airport.
But, I am guessing you want to get to the magic! You should arrive by 9:00 p.m. to Wilderness Lodge. You can head to Roaring Fork (food court area) or you can make a late reservation at
Whispering Canyon Cafe. Your teen boys might enjoy this location with its All You Can Eat platters! While I cannot guarantee there are still tables available, I just checked and there were 9:15 p.m. reservations available, which might work well for you. Roaring Fork is quick service, so reservations are not needed and usually food courts remain open until at least 11:00 p.m. or even midnight.
I hope you and your family have a magical WDW vacation!
