1. Darth Vader (but he had Storm Troopers with him so I'm not clear what the difference is...)
4. Naboo (noooooo not Jar Jar! Sad...)
Glad to see you liked the ride.
As for ride combos, Robert has already started a discussion thread with a poll of all the ride combos. Go ahead and add your vote there.
1. Darth Vader
2. the Wookie planet, whatever it was called
3. Princess Leia
BTW, on my ride, once the Star Speeder landed on that floating platform at Coruscant, I couldn't help but say out loud that dumb line from Revenge of the Sith: "Another happy landing!" lol.
