This is a fun festival. Lots of balloons (probably about 20), tons of food and drink vendors, bouncy castles for the kids, and a live cover band. I've been 2 years in a row and will probably be going again next year.
It looks like there are a few poor reviews, however they were from earlier years (2013 and 2014). I went in 2015 and 2016 and have no complaints.
