Funnily enough, I've Done almost every ride in each park, but here are the few that I don't bother with anymore.
MK
Enchanted Tiki Room UNM (Don't hate it, but don't want to spend time with it)
Aladdin's Magic Carpet's (got dizzy the 1st time, don't want to relive that.)
Hall Of Presidents (Actually like the show but same as above)
Peter Pan's Flight (wait is alway's HUGE when I'm there, good ride otherwise)
Snow White's Scary Adventure (It's okay, not worth bothering though)
Cinderella's Carousel (Kid ride)
Dumbo (Kid Ride)
Winnie the Pooh (Wait is a tad bit too long)
Tea Cups (kid ride)
Toontown (No Explanation needed.)
Indy Speedway (Too long of wait, not worth it,)
Astro Orbiter (Don't really care for it.)
Monsters Inc. Laugh Floor (Really hate it)
Epcot
Parts of WS (No time when you've got a fastpass to Soarin')
DHS
RNR (Never did it, probably never will)
