When you and your family walk into Star Wars: Galaxy's Edge this Summer, only one of the two attractions will be open: Millennium Falcon: Smugglers Run. Your kiddos will need to be at least 38 inches tall to ride, and there's no word yet on if the attraction will offer Disney's rider switch service. When Star Wars: Rise of the Resistance opens later this year, kids will need to be 40 inches or taller to ride.
