I have a few things to add & a bit about Scare Actor dining THIS year, as info for that was quite limited in my opinion, plus my opinions as a first timer who took kids (yes, I was the jerk!)! ;-)
We had 5:15pm ressies for Scare Actors Wednesday the 17th. My kids have done Haunted Houses in Denver & loved them, and second being so far away, I'm not sure when our next vacation will include USO, and I always want to experience everything that we can. If we only made it through 1 or 2 houses, and the kids had some interaction w the Scare Actors at dinner, then I would call it a successful evening.
We arrived at USO about 330pm, about 1.5hour later than I would have liked. However, lines to get in were minimal, which I was very worried about. We got in and went towards Simpson Land, as we missed most of it the evening before. We immediately ran into Beetlejuice, and I was more than excited. No line for pictures, he was great. Very funny.
Did Simpsons w 20min wait, had my Flaming Moe sat for a bit bc it was screaming hot & then walked back around towards Monsters about 445pm.
They did not give anyone wristbands, but they were scanning tickets to get into the holding areas. We walked past Bennys, the holding pen to the right of that was already mostly full, had to get someone to open the gate to let us through to the entrance of Monsters Cafe. We got there, gave them our tickets & they put us to the left of the waiting area outside, the 5pm group was to the right, already lined up. Igor came blazing by, gave everyone a laugh & 5pm went in about 455pm. They then let our "group" go to line up. As we were one of the last families to check in for our time, we were in front of the "group" as everyone else had stood back in the shade & sat down to wait. We had one older couple who pushed past us to get in front of us to be front in line. And then a family behind us in line was obviously annoyed with us too. To be fair, I didn't know that is how it would work, and we checked in closer to our originally time. But I could tell then that this was going to be feast or famine! Hahah
We waited in line for out turn to go in, FOR. EVER. In the direct sun. My husband was dripping sweat, I was melting (and I rarely complain about the heat) it was brutal. We got past 515pm & at 520pm a CM came over and said at 530pm they would start taking us over to ST OR Poltergeist when we were finished eating. I wasn't quite sure what that meant, but it sent me into a small panic. We hadn't even started eating, 530pm was pretty early to start lining up, when would they open the pens, ahhhhhh. Right about then they opened the doors and we went in. Game plan was to load up the trays & plates with as much as we wanted to eat or try, so we didn't have to wait in line for 2nds or waste time. We got sat towards the left side in a half round booth, which was good as the SA seemed to be coming from the left. We sat & started shoveling in food. Sam was playing a lot w my kids, peeking over the wall, super cute. The Purge lady came and sat down & did some fun stuff to my daughter (huge Purge fan here so I was thrilled!) & my son stood to take a picture.
Igor then jumped onto the booth bench, behind my son & next to me. BEST thing ever. He sat w us for almost 4 or 5mins & just talked to us & played with the kids. Super funny & he def made me jump (almost never happens). We had kids go to the bathroom, in case we were in line for 2hours, which worked well-there was no lines inside the cafe.
We got a little interaction w the Witch from ST, Sam took pictures w us, and the Vampire never stopped for us, but did make my kids jump a few times. At that time the CM came back around to tell us the line was open for "us" over at ST when we were finished. We asked her what that meant exactly, and she said that they would take us over to the line. I asked about the regular gates opening and she said oh no, that is still 6pm. And then I asked about the holding pens & she said something about we would get in line with the first holding pen. Whatever, it seemed like we wouldn't be just let loose & that it was actually in our favor that we did the dining. But-I wasn't taking any chances. So we finished shoveling food in our mouths, grabbed a couple cookies & a full drink each (hindsight, was a terrible idea), threw a $20 on the table & ran out. We walked out towards the left & the line of people in front from the pens walking into the queue was long, but moving. No running, people were lined up orderly.
We asked a CM about the "line" for SA dining, and a CM w a headset (nicely dressed, not just a kid or whatever) walked us over to the entrance of the line, and let us right in, basically merging into the line. BRILLIANT. Best guess were, we walked out of Monsters right about 550pm, and when we stopped for the first time in the line & I looked at my phone it was 552pm. Husband had seen the board that said wait was at 70mins as we got in line.
So, after I had time to reflect, I think it ended up being a good option. Food was buffet food, but I thought it was pretty good. They had several choices, mostly fresh & plenty seasoned. When I went back to grab cookies, there was no line at all for 2nds. The CM was like yes yes yes take a drink, take some more cookies, very nice.
I probably would have slowed down just a smidge when it came to eating, or tried to get the 500pm time, so that we had a full 30mins at least to eat & see the SA.
And to me, it was def worth it to sit inside with AC to wait & have a quick bite, plus bathrooms to use before we jumped in line.
From time we entered Cafe to time we jumped in line, I would say it was about 30mins total.
