Last year we took our 4 year old and 18 month old sons, and they both absolutely loved it! We used a double stroller, since there's alot of walking around and then sitting in chairs. I'm not sure exactly what the ear protection they wore is called, but they look like huge ear muffs. It is like what you see people wearing at a gun range or the airfield ground workers wearing. We thought ear plugs would get pulled out and lost too easily. We wore ear plugs ourselves. They both had a fabulous time, and are looking forward to going again this year.
