Good question. For me I’d say anything that resembles a simple themed or unthemed carnival ride. So at DCA that would be Zephyr, Jellyfish, Silly Symphony Swings, Emotional Whirlwind, and Jessie’s Carrousel. Or in other words, any unthemed ride that just goes up and down or spins in circles. I don’t think the Pal Around fits the description. Maybe a tiny off the shelf Ferris wheel like the one you might find at a Carnival. So that’s 5 at the pier alone. I’m sure people will say the trackless tech disqualifies Luigi’s from being classified as a flat ride. So that’s 7 in my book with the Cars Land rides. Which admittedly are both charming and have highly themed queues. They re themed as such that makes them feel more like Dumbo or the Tea Cups. I think it’s quite the feat to give a flat ride so much character that it doesn’t really feel like a flat ride.
