We did it last week and it went well. Entered through the gateway around 7:45am. Checked in at the tour desk around 8:00am. We actually waited for some no shows. There were only 15 in our group. It was a nice sampler tour. I got the impression it was a sample to get you to book other tours because at least twice the guide asked is anyone was ready to book one of the other Epcot tours.
