I don't force, but I've convinced, pleaded and yes, guilted, even bribed (maybe a little white lie tucked in too).
Since it's just my son and I, if I want to ride something, he has to come with me. The two I've "forced" were Radiator Springs Racers at
Disneyland (I knew he didn't like test track so this was where the little white lie came in - and in my defense, it doesn't look like it's going as fast as it feels) and Mine Train.
He hated RSR, LOVED mine train.
I tell him that I really want to ride, I can't do it without him. I promise he will be safe, it's slower than I drive (and slower than TT and RSR) and I would really appreciate if he rode with me. He LOVES the mine train. Talks about how it's the best ride he ever rode.
Oh, on a trip when he was younger we had 2 days at AK. The first day he rode the safari he was fine, the 2nd day, he was panicked about going on. He'd somehow managed to convince himself that the rickety bridge (which I don't think is even there anymore) was way longer than the maybe 20 seconds it actually lasted. Once I convinced him that part was really short, he was able to ride again (and now believes me when I say his memory is wrong).
That said, if he's still said no after all my cajoling, we wouldn't have ridden.
