Thinking of doing this tour and my mother in law and mother would like to join us. While I understand that it is a whole day, 7ish hours covering Magic Kingdom, Epcot and MGM the moms do have a few problems. Mom in law has bad knees and does use a cane for assistance and my mom can have sore feet from walking too much. They really want to do this tour so I am just trying to find out from others if there is way too much walking or is the walking offset by sitting etc. I also understand that the bus will drive us too the other parks, do we just get off at the main entrance or does this but take us into the park to save on the walking - Thanks any and all help would be greatly appreciated!!
