Hey there Peggy,
Welcome to planDisney and thanks for your question! I always love the opportunity to answer a question from a fellow Arizonan.
Star Wars: Galaxy's Edge is one of my favorite lands in all of the Disneyland Resort. The galaxy far, far away is located in Disneyland Park and has the two attractions you referenced as well as some really great shops with unique gifts, delicious food that's out of this world, and some of the best character experiences in all of the parks!
Millennium Falcon: Smugglers Run is a flight simulator ride where you and 5 other Guests get to take up roles in the cockpit of the iconic Millennium Falcon. There are two pilots, two engineers, and two gunners, and you are on a mission for Hondo Ohnaka to deliver some goods....discreetly. This is a one-of-a-kind attraction in that you and your flight crew actually control what happens while you ride!
Star Wars: Rise of the Resistance is my absolute favorite attraction, hands down. The majority of the ride has you and a group of other Resistance recruits riding in a transport trying to escape from a First Order ship. However, there are plenty of other fun surprises that await you during the experience! This attraction continues to take my breath away every time I experience it - it is absolutely incredible. Of the two rides, this one is a bit more thrilling and does have a mild drop near the end. However, my little one has experienced it and enjoyed it, so it's not too scary!
Thanks again for your question, Peggy. I hope you have fun visiting the Happiest Place on Earth and tell Kylo Ren that I said "Hi!" when you see him!
Have a Magical Day,
Greg
