So we were at the park today for a VERY short trip and while in line for the Matterhorn, someone told me that the Matterhorn bobsleds are the old trains from Space Mountain at Walt Disney World. Is that true? I've never heard of that before and it seems weird that only seatbelts would be allowed for Space Mountain. Anyone have the correct answer?? I doubted it was true, but I guess you never know! Thanks!
