I'm getting married at Navy Pier (near the carousel), but we are looking for somewhere to host a dinner with a set menu for 20-30 people afterwards. This is walking distance and would be nice if possible!

Yes, definitely you'd need a reservation. I've been on Mystic Blue couple of times. Great experience! There are multiple options for boat trips and celebration. Feel free to check all including Odyssey. You'll be happy with any of those options depending on final package and price. Enjoy your wedding dinner at the Chicago Navy Pier boats!

I worked on the boat for a year. You just have to call ahead of time if you want a designated area or floor for your group

Nice ride and good food

Yes it's very nice their and the boat it's nice.
