Small World is a close 2nd...not a fan of the ride, but I love me some Christmas lights. This was from our 2018 trip as well.
I just love standing in the evening and watching them come on. I do like the overlay on the ride but I hate the * 'toons* they added. (When was that? '07 or '08 I think.)
Rod and I with our mothers in 2002. When our daughter (then 24) found out we were going she declared "You're NOT going to Disneyland with my grandmas without me!!" She hopped on a plane and came down. Those were the days; even she had a PAP.
