We love Disney Quest. I liked it before we had kids, and we like it even more now. My kids are 9, 8, and 2 and they had a blast. We have a premium annual pass right now, so that's how we got in.
As for minigolf, I've done the winter/summerland and the Fantasia one. It's a nice cooler night activity, slower and a change of pace. We don't often do it because of the extra expense, but it's fun.
Can you offer your tickets to someone if you're not going to use them? I often give stuff to people like that, although sometimes they think I'm a crazy person, lol!
