As long as you don't receive a cancellation phone call, there's hope! Just make a back up plan to have up your sleeve if you need it. How about sundaes at Ghirardelli's? Or if you can snag a reservation for the Pixar Afternoon Tea at S55 for that day? Or TF on Main Street followed by ice cream at Gibson Girl (now with mobile order!)? Or you can plan a different kind of Dessert Party: if you can get a reservation for 9 pm-ish at Catal on the upper level patio by the railing looking toward Wetzel's Pretzels, you'll be able to have dessert while watching fireworks. That might be fun for the girls. If you have a video of TF ready to go on your phone, you can sync the music to play as soon as the show starts. We did that for friends with RDCT -- they couldn't affort tickets to DL, so we took them to Catal for dinner, they had no idea the fireworks were going to start, then we cued the music, the first fireworks went off, and... Magic!
