Sometimes it's not the bathroom itself, but the associations you have with it.
Top Ten Toilet Highlights
1. The Boardwalk concierge/reception area. Just lovely potties. Spotless, private, more executive washroom than overflowing trench, everything a toilet aspires to be.
2. MK New Fantasyland - Behind Gaston's Tavern. Immaculate, empty potties.
3. The restrooms between Pioneer Hall and the Trail's End Restaurant at Ft. Wilderness are great. Clean, lightly used and for me, always associated with either the Hoop Dee Doo Revue or a relaxing Mickey waffle breakfast. Really any Ft. Wilderness restroom is a joy.
4. On the ground floor of the Polynesian, by Capt. Cook's there's another set of restrooms that I frequent. Again, they're clean, only slightly busy and I associate them with getting a Dole Whip for dessert and wandering out to the beach to watch the Electrical Water Pageant or fireworks.
5. Before entering EPCOT, kind of between the bus stop and the monorail exit, there's another lightly used restroom. With little kids, we always stop to pee before getting in the lines to enter. I suppose it's the anticipation.
6. Another EPCOT spot, the Odyssey restrooms. Again lightly used and the place we stop before the long trek back to our resort after Illuminations.
7. Final EPCOT spot, the restrooms behind Imagination. No one goes there. Empty.
8. MK Main Street toilets near City Hall. In the early AM, it's pretty busy, but two things. Last time I used it, it was a little dated, maybe retro early 90's Disney. The feels. And the anticipation of starting a day at MK.
9. MK Main Street again - toilets between Casey's Corner and Crystal Palace. Again, lightly used. Just a great place to fill a water bottle, sit down and rest.
10. MK Tomorrowland between CoP and Space Mountain. Strangely, lightly used toilets....
Intestinal disappointments
1. The world's fanciest loo - the Tangled Toilets. Theming doesn't save it from being overcrowded and dirty at all times.
2. MK Fantasyland circus toilets - wet, filthy, smelly, crowded. Bleck. Newness doesn't save it from grossness.
3. Disney Springs Marketplace toilets by Once Upon a Toy - again wet, filthy, smelly, crowded. Double - barf.
