For myself: I'd be torn between iasw and TTA. iasw, though not my favorite, always makes me feel like I'm at Disney. While on TTA, not only do you get that, but you at least get a glimpse into SM and Buzz.
Okay, I've convinced myself. If it's during the day, iasw, if it's dark TTA, with those great views of the castle lit up, oh, especially as Wishes is going on.
DW: Probably RnRC or FOTLK
DS7: Space Mountain, feel bad for DW about this, because I hate that ride. Only been on it once and felt sore afterwards, so I haven't been on it again. Probably when DS3 is tall enough, I will.
DS3: Test Track, he was screaming faster faster. He always wants to ride the fast rides with me, and he even told DW "I ride with you mommy", trying to get one last ride in during our trip last year.
