Yes. However it requires being part of a Grand Gatherings Group. There are two possibilities.
The first starts at the Contemporary Dock about 1.5 hours before Wishes! There is an area set up next to the dock with the bufft and visited by Captain Hook and Mr. Smee. After about 3/4 hours of eating, visiting, photo ops, etc., you are given a very large chocolate chip cookie and board the boat, which seats about 100. The members of your GGG are assigned specific seating area. There is a "Pirate" on the boat who leads in fun and games (with prizes). The boat will pull out and anchor near the Electric Water Pageant while it is showing outside Wilderness Lodge. Then it will go over the bridge into Seven Seas Lagoon and anchor on the extended centerline of Main Street. The music and narration will be heard through the boat's speaker system. After Wishes! are over, the boat will go back to Bay Lake and the Contemporary Dock and be met by Peter Pan. The cost, last time I went, was $30 per person.
The other is the Epcot International Buffet which starts at about 6:45. It is in the World Showplace (former Millennium Village). Your group is preassigned to one or more specific tables. There are four large buffet tables, each featuring the foods of a different country. During the evening there are acouple of "Streetmosphee" people holding interviews and making sure a good time is had by all. There are children's games and visits by characters. About 8:30 the entire group is led to the water-level landing area at either UK or France, where a buffet with bevrages is set up and available until the end of IllumiNations. Last time I went the cost was $60 per person.
All of the attendees to each of these gets a pin. I do not know if there is any discounted price for children.
