Depends on the ages of your party. We are two adults and were not impressed with AS2 at all. More for small children IMO. Toy Story Mania is fun.
Depends on what you make out of it. Me and my much bigger 14 year old son spent the entire ride squishing each other in a significant, intentional, over-reaction to the whipping motion. We had a blast and laughed as much on that ride as we did any other the entire visit.
Was it a 'thrill' ride. No, absolutely not. But, we found a way to create an experience we will remember for a long time.
