I just found and read your whole report! We also did a Dec 2019 WDW trip, with two boys ages 8 and 3. They loved everything Star Wars even though my youngest was too short for ROTR. We asked to wait for a booth at the Cantina and it didn't add too long to our wait, but maybe we just got lucky or maybe they took pity on me because my little one was too tired to stand. That cookie was gross. I've never seen my kids reject cookies but they were both not having the one that came with the blue bantha. We didn't take the booth space up for very long though because my eldest had to get to Jedi Training. We built droids and to my amazement they still play with them sometimes. There's a new app that enables you to control the droid using your phone, play tic tac toe against it or even teach it a choreographed dance (better with the R2s, of course). Other than the expensive droids, we managed to find two cheap-ish souvenirs in GE, the small plush shoulder Porg with the magnet, and a deck of Sabacc cards that we still play with. I think they were between $15-20 each. It's nice to reminisce a bit about that trip. It really feels like it was a lifetime ago.
