I was also there on Monday night, and it was a really great night. We entered just about at 7 pm through the event gate, and grabbed food/caffeine (we were at rope drop in Hollywood studios that morning for Rise of the Resistance), and sat in Adventureland for a bit to plan our evening. We had grabbed a fastpass for the carpets on our way to the park, so we rode that first (there was still a 10-15 minute wait), then went up to BTMRR where there was a 15 minute wait, but that had us on the ride just as the fireworks started. We jumped right back on to no wait (by now, only DAH ticket holders could get on), and then were allowed to stay in our seats for ride #3. It was starting to rain a little, so we went to Jungle Cruise then Pirates, and both were walk ons, and when we got off no more rain. had our only reali hiccup of the night before getting on Jungle Cruise, because the snack cart hadn't been stocked with drinks yet, but we were able to grab them (plus some ice cream) after Pirates.
From there, we went to the Haunted Mansion (walk on), then met Tiana & Rapunzel (we must have caught a shift change, because we waited about 15 minute here). Jumped on the Mine Train, where it was posted as 25 minutes, but we were off in less than 20. Rode Pooh as a walk on, then split up so I daughter could ride Speedway (said there was no real wait) while the other one went with me and we walked in to see Ariel, then walked onto her ride. Met up with daughter #1 at Space Mountain, where we walked on (sensing a trend yet?), then did the same at Buzz. We split up for our final ride, with daughter #1 riding the Oribiter while daughter #2 and I rode People Mover. On our way out, we grabbed popcorn, sodas for the next day, and ice cream.
As expected, the worst part was the wait for a bus then the LONG ride back to the Beach Club (we were the last of the 5 Epcot resorts to be dropped). We got to the bus stop right at midnight.
We've done AH events before, and this one was really good. I know it was because of low overall crowds and cooler weather that we had such a good night, but when it's this good, it's REALLY awesome!
when asked, "What time will they let people in for MY event?!" Decide what is most important to you - being there right when they start letting people in or relaxing in comfort until you KNOW you can get in. Then arrive at the appropriate time. 
I would make fastpasses at 6, 7, and 8, or 5:30, 6:30, and 7:30 if it wouldn't let me make one at 8 for some reason. BUT, I'd make that first fastpass my least important one just in case.
