My wife and I wanted to try out improv acadia as we always visit second city in Chicago when we go. We were pleased to find out that the comedians at improv acadia actually work for second city in the off season, which would explain why they are so awesome.
We called our reservation in about 3 hours ahead of time, but we were in the middle of the week and have been told that during the summer and weekends you need to reserve ahead of time. Tickets were cheap and the food and beverage menu was reasonably priced compared to much of the other restaurants in town - great apps and drinks. Get there 30-45 minutes early to get the best seats and your tab going.
As for the show, we had 3 comedians and a musician and it was off the chain. The comedians take cues from the audience to help spice up the show, including writing a shakespearin play "mad lib" style, and doing an impromptu story on how one of the couples in the audience met - in this case my wife and I. Hilarious beyond measure.
We stayed after the show to have a drink with the cast and they are all very interesting people from around the country.
Overall this was a great time for the low cost of entry and refreshments, hard to believe this caliber of entertainment is hidden in a little resort town!
