We just did this tour in August and LOVED it! My kids were 5 and 4 and despite the heat, they were really into it. It is about 2 hours long, but there is a short break in the middle for drinks, bathroom, etc. We thought it was well worth the money and it gave us a perspective of MK we hadn't had before. If you want more details, please PM me. Hate to give away the ending to anyone who doesn't want it!
