I made it to Batuu at WDW last week. I probably don't have anything really new to add just my personal thoughts and experience.
We built a lightsaber at Savvi's, Got numb tongues at Olga's, piloted and engineered the Falcon, got hassled by imperial thugs, sampled the local delicacies, checked out the local wears, and chatted with a resistance spy.
After watching Chewy getting mobbed at every step, I actually started feeling sorry for Vi Moradi. She was doing a great job staying in character slinking around only to have guests ask her for directions to "the bar". So I took some time to read her
Wookieepedia entry to have a proper interaction with her. She definitely did a double take when I addressed her as "Magpie" and told her I had a message from "friends" in the "Illenium" system, but I'm fairly sure the reference I made to freighter "THX1138" was a bit too obscure for her.
Overall I kind of have a "one and done" attitude to Galaxy's Edge, or Batuu, or Black Spire (why does it have three names?) leaving Studios in fourth place on my "parks to visit list" when going to WDW. The Falcon is only fun as a pilot, the food is nothing special and I don't see needing more than one Lightsaber anytime soon. Perhaps "Rise of the Resistance" will change my mind. Time will tell.
