I haven't read this whole thing but I'm going to jump in anyway!
First off, I have never been to Universal since frankly I always think of it as similar to Six Flags that I live an hour away from that my kids have never been to either. It has never been anything to do with Disney (our first trip was only this summer), it has was their advertising that made me think this way.
I only remember seeing the big rides and frankly nothing that would appeal to anyone who was not a certain height. Plus they all looked like they were more on the "scary" side to me (I remember the Frankenstein ad & I think isn't there Jaws there too?).
My 11 year old is just now at the height I think of for *maybe* taking her to Six Flags - even though they supposedly now have a kiddie section (It's ingrained in my brain from when I went as a teen that it basically was for the taller/thrill ride crowd - and back in the day it was Marriott's so it wasn't even a Six Flags then. LOL!). I hated the thought of paying $50 so my kid could ride 1 or 2 rides.
Just wanted to give a perception of a non-crazed Disney person that my perception was totally based on what I saw on the few ads we get for Florida parks (although I did really like our vacation but DH doesn't do *any* coasters or too rough rides, so I can't even imagine him agreeing to Universal - he begrudingly did Disney!). This was way before I even read anything on any website or did any researching on any vacation.
Then again, after our Disney experience it will probably be a very long time before we make it to Universal as my DD *hated* TOT - loved RNR and my 8 at the time guy freaked out on Stitch so bad that he refused to go on any ride that he couldn't see *what* it was from the outside and didn't do any coasters whatsoever - the CM had to convince him to go on Spaceship Earth; he freaked before going on Figment so DH had to exit with him before going on the ride, etc... (It will be a long time before we make it back to Disney too). We didn't do Space mountain.
I came over here though to see if maybe we would want to check it out when we are in Florida since it will probably be about 3 years. This post caught my eye.
