Couple others I just thought of - stop by the gift shop outside of Jungle Cruise and ask for a “Citizens of
Disneyland” pin. Also in the same gift shop, but closer to Bengal Barbeque you can get your fortune told by ”Trader Sam” - I believe is is 50cents.
Pressed Pennies are always a hit.
Snow White‘s wishing well - I love this spot at night, and you can hear her sing.
Autopia used to have an inexpensive “drivers license“ you could get. Not sure if that is still a thing or not.
Could also do some research on unique things to DL like the Julie Andrews horse on the carousel. If you are so organized an inclined you could do a scavenger hunt - pretty sure there are some online you could find if you google it.
Also in Galaxy’s edge you can do all the interactive things with your smart phone or tablet. My boys could spend all day there just deciphering things, etc.
One of my favourite things is to simply head to the Grand Californian and sit in the lobby soaking up the ambiance and piano player. If it is crazy busy head up to the 5th floor (I think it was 5th, might have been 3rd) and there is a nice area with seating.
(You‘re getting me excited about my upcoming trip, lol!)
