I haven't done the this particular tour but I have done the one in Celebration which was really great. A long tour - almost two hours - all around the beautiful houses and green areas of Celebration and cheaper than the Epocot tour.
I have done the tour that goes around clebration they are on the 192 just before old town and where you see a sign for Dipping Dots ice cream , I wonderful tour and we are booked to do it again this year .
