Matterhorn

The Matterhorn Bobsleds attraction actually has two different queues one that begins on the Fantasyland side of the mountain, and one on the Tomorrowland side. The queues are entirely outdoors, though the final portion of the queue is covered. The attraction itself has two different tracks, and which one you ride depends on which queue you choose. If the timing is right you'll be dispatched at the same time and can "race" the bobsled next to you.
The bobsleds will seat up to four people seated single file. They have two compartments, which will each seat two friendly people -- the larger passenger should get in first, and the smaller passenger will sit between their legs. It's not a very comfortable seat, especially when the ride starts bouncing around. The person in the back has a back rest which helps, though. Each passenger has their own seat belt. These are NOT retractable seatbelts -- instead it's a long strap that buckles into a shorter strap on the opposite side and you must pull or loosen the strap to adjust it to fit.
After leaving the boarding area the bobsled goes up hill, then comes down the mountain. There are many tight jerky turns -- this is definitely not a smooth ride. Inside the mountain there's several encounters with the Abominable Snowman before the bobsled eventually splashes down in the lake and proceeds to the unloading area.
