My daughter (7 years old) and I attended the FEA Dessert Party this past Wednesday night (4/11/18) and had a great time. We showed up a few minutes before 8 and only had to wait behind one large party checking in ahead of us. We were soon taken to our table, where we were seated with a mother, daughter (5 years old), and grandma. The girls made friends quickly, and largely kept each other entertained. The dessert offerings were robust, and there was also a large table with cheese, fruit, crackers, etc. There was also a stand where a CM was making caramel popcorn with liquid nitrogen, which was cool, and my daughter loved the fact that you could breathe out smoke through your mouth and nostrils after eating it. Finally there was a table featuring scooped ice cream, a s'mores pudding creation (delicious, but very sweet), and a salted caramel cottage pudding. In addition to an array of juices, there was also a bar with several choices of beers and wines.
Our table was right up against the railing around the World Showcase Lagoon, so we had a perfect view of Illuminations. CMs also passed out glasses just before the show that made the fireworks look like snowflakes, which was a cool tie-in to the Frozen theme. A few minutes after the show, we were escorted as a group over to Norway, where we went through the FP line (it didn't matter since the park was closed at that point and there was no one left in standby) and onto the ride. We rode FEA one time with no wait, then were able to stick around and take some photos as the whole area was empty.
Overall, I thought the FEA Dessert Party was a very good experience. The desserts were tasty, there was unlimited beer and wine, the view of Illuminations was perfect (and it was great to be able to sit down the whole time), and we got a no-wait ride on FEA. I would recommend it to others if you feel like this would be up your alley. Happy to answer any questions anyone might have.
