I totally get going to the characters without kids

I'm into too! (but my boyfriend isn't), so what we did (twice so far) is, the first day he sleeps in and I just go for the characters, head back to the hotel and have breakfast together. The second morning we'll go together and do the rides.
I'm pretty sure you'll be able to do all the things on your list in 4 EMT mornings. One time I went with friends and we entered the park at 9:30, one is in a wheelchair, but we were one person short on her EAC, so our plan was that I'd get in the normal line for Space Mountain just before rope drop and I'd be in front when they'd be at the back entrance. But there were so little people in line that I took the ride before rope drop.
Although I just realize they've changed the EMT hours since I was there last...
