I'll chime in on this one as I'm a middle age parent who goes solo with DS13 a lot and I didn't want him to constantly ride alone (though he has when he decides to go on EE for the FOURTH time in a row - um, no thank you, my brain was quite addled after the third time around). I do not like roller coasters or anything with huge drops. Expedition Everest is about as far as I will go in terms of roller coasters. I would definitely put Barnstormer as more wild than 7DMT. 7DMT is all wind-up with no pay-off (pay-off being big drops and, I'd like to thank the Imagineers for keeping them out of that ride). Slinky is deceptive. It can feel really fast and intense depending on where you sit, but it is SUPER smooth. I would definitely rather do Slinky than Barnstormer - again, no huge sudden drops, woohoo! And the drops that are there are really, really smooth - no jerky Barnstormer stuff. Space Mountain, oh dear, I hate it so much. I found if you count to 100 at a fairly steady pace, the ride is over once you get to 100 - no joke, that's how I get through it. BTMRR just feels fast, but no big drops - yippee! Splash - yeah, it's lovely until the drop. I think the only good thing I have to say about that is the drop is over really fast.
