You know one tip that should be included in my list?
Look up. In Frontierland, you'll find charming balconies like this one over the Rancho del Zocalo restaurant (you can probably tell - we eat there a lot). In New Orleans Square the balconies showcase rocking chairs and sometimes, folks will throw beads at you. In the stores even, there are often lovely displays around the top few feet of the walls. Keep your eyes peeled, they barely leave an inch untouched at Disneyland. I'll post some of my "looking up" finds over the rest of the week.
