This sums it up!
We were there from Oct 1 - 10. We had a blast, but yes at times the lines were a pain in the rear (especially in the heat). But we never really felt unsafe. For the most part, distancing in the lines is good, and because guests spend so much time in lines, walking around the parks didn't feel all that crowded. The only park where we could really feel the crowds was MK, especially on our last day - Sat the 10th. That pretty much felt like a normal day to us, crowd wise. But, again, we didn't feel unsafe with all of the protocols Disney has in place.
Now - we've stopped in Charleston on our way home for a few days and what a difference. I looked at my husband and said, "we aren't in Disney anymore!". Very few people wear masks on the streets, despite a city wide requirement for them. Some restaurants still have tables close together, etc. While I will never say Disney is doing things perfectly, after being in that bubble for 10 days stepping back into the "real world" is a bit jarring.
