I just got back from riding it over and over and over again. It is wonderful!!! I now have a new favorite attraction. My description is as follows:
The Yeti is pretty intimidating for sure. It appears as a shadow first in the first half of the ride and then at the end he appears in person (huge and VERY VERY VERY lifelike). The ride is by far the best ride at Disney World in my opinion!!! It is very very fast but you don't particularly notice the speed as much because it is going around and around (like in thunder mountain railroad) and you don't really notice the drop like splash mountain because again it isn't straight, it's curvey. There are no upside down loops. The ride is much smoother than thunder mountain and space mountain .... more like rock-in-roller coaster as far as it not being real bumpy. I absolutely loved it!!!!! And the view from the top of it is unbelievable. I was hoping we'd get stuck on top! I loved the individual lap bars too because unlike other rides, if one person has a good size belly and the person next to them is a skinny child, the poor child's lap bar isn't even close to their lap. This ride prevents that from happening. Also, they even have pockets in the front for your purses, water bottles, backpacks, etc. so you don't need to hang on to them for life like space mountain, etc. I kept my glasses on and they were not joggling around on my head. Hope this helps with everyone's questions.
