Thanks for all who replied, We have all been on Spiderman, and your right, it is a very jerky ride, so we are re-thinking that one, the only other one we wanted to take him on was the Simpson, which we have never been on, but figuring it was a lot like Men In Black, (because it's the same building), didn't think it would be too much for him, since he loved Buzz Lightyear, MIB was very similar. Never even considered taking him on Dinosaur, that would scare him to death. We would never consider putting him on something that would scare him or put him in any danger, we have all been to Universal / WDW many, many times and know the rides very well. I appreciate the suggestion of Healey's (spelling?) but he would be more dangerous on them (with the wheels) than on any ride we could put him on.
We have already agreed that if he dosen't make any height restrictions, he is not going to care, we will take him back next year! and YES- he is turning 3 a couple of weeks after we get back from Disney trip! (Don't know who remembed that one! I guess I'm on these boards too much!) Thanks ALL!!
