Hey, the spinning is not for everyone. My wife and I rode the green side to test the waters first and it is just like Star Tours. In fack a bit tamer than ST as you have the shoulder bar holding you snugly in place. There really is no way you could get on the wrong version, unless you completely blow it. They are on different sides of the building, have different pre-show film sections, and the orange side has multiple warnings and chances to exit.
I rode the orange side 3 times after the green and had a blast. My Wife, however made it about 3/4 through the orange side when she looked to the side and got almost overcome by her pesky motionsickness. After sitting through the next ride sequence on the bench at the exit (and being offered a glass of water by the CM there), she was fine.
The green non-spinning side is something they just starting offering around the end of June or July, so I don't think you had a choice last Dec.
I highly encourage people to at least give the green side a try, it is a wonderfull attraction. And if you do try the orange side, just focus on the screen in front of you, press your buttons, flip some of the switches at random, and don't close your eyes longer than a blink or two.
One more little known secret. To lessen the effects of the g forces, flex and release your thigh muscles every couple of seconds during the bad parts. It forces blood to flow a bit more normaly.
