American Adventure for me. It is just so relaxing in those chairs. And I love the show. It is epic.
As far as I know that is the only attraction this has happened with me. Certainly never on a ride, just on a show.
As a parent of 3 kids that often takes all 3 to parks by myself due to work schedules and willingness, I will not lie.
I actually leverage some rides JUST for the ability to catch a break.
- Carousel of Progress. I love this ride, but I've ridden it so many times, I can squeeze in a nap from time to time.
- Muppet vision. Same as above, great for a snooze.
- Disney adjacent: We saw the new Minions movie when it came out a couple weeks ago, and I battled my eyes the entire movie. I saw it again last week at an event for one of the kids, and I realized I actually must have slept all the way from the opening credits to closing credits, lol.
-Pretty much any show from frozen ever after, nemo, FOLK, etc, is likely I may have snuck in some very long blinks.
I'm sure there are others that will hit me.
