We have done The jingle Bam dessert party in 2016,2017, and 2018. It’s a fun treat! We usually get a table service reservation at prime time or sci if for a late lunch at 2 or 3 pm. Or at Trattoria on the boardwalk at 9 :30 pm. Saving our quick service for a Mickey waffle breakfast later in the trip. 2 years setup was in front of the Chinese theatre. ( not sure this year with Mickey railroad). Last year food, drinks, and Santa Goofy were inside Pizza Rizzo since light rain shower.
We liked the sweet treats - cookies, choc fondue and marshmallows. My Hubbie loved the French onion dip and chips and some of the savory sides. I liked the hot cocoa and adult drinks. Grab a to go cup with lid early in the party , so you can take an extra drink when you leave. It was nice not having to setup an hour before to see the fireworks . Also nice not to be elbow to elbow. We sat on ground for 15 mins. Then stood, with kids next to fence around shrubbery to watch the show. Any questions let me know. Have fun. And oh yeah, we booked this like 2 months ( 4 months out) after we did our ADRs
