I'm really not a fan of some of the classic, fan-favorites
1. Jungle Cruise - the puns just don't appeal to me and I think it's generally boring and a waste of time, oops!
2. WDW Railroad - again, kinda boring and a waste of time
3. Astro Orbiter - I hate how it feels like it's going to tip you off, and the line is always ridiculous. The views are nice though.
Some of the most disliked rides I have a weird affection for, like Magic Carpets and Barnstormer. I know Magic Carpets are just a spinner ride, but I like that there's camel spit to try and avoid. I used to ride this all the time on my DCP. And the Barnstormer is super short, but it's such a fun little coaster!
