We went to the parks 3 times this past week, DHS on Wednesday (also had Passholder PlayTime at TSL), MK on Friday, and AK on Sunday. We also visited AKL to eat at the Mara after our trip to AK.
The parks were as quiet as I've seen them in a long time. We did our TSL "preview" which was excellent and allowed us to walk on the rides as fast as we could walk the queues and have no longer than a 1-2 group wait ahead of us for character meet and greets. Then we walked to Jedi Training Academy once the regular guests started filing into TSL and got into the second show of the day (they were still doing signups for the third show when we went back to get ready for the show). The meet and greets for Olaf, Minne, and Mickey were basically walkons as was Star Tours. We also got a reservation at the Sci Fi Dine-In the day before, along with a Slinky Dog FP+.
MK was similarly quiet on Friday. Even though we didn't have the benefit of EMH, we still did very well, likely in part to the MNSSHP keeping people away. We rode BTMRR at Frontierland rope drop, then Splash Mt which had technical issues for about 10 minutes but did start back up again. Ate at Gaston's where the lines were nonexistent and there were plenty of empty tables to choose from. We rode the carousel which was maybe ~30% full and watched Philharmagic with a few dozen people. We used a FP+ for Haunted Mansion but when we got to the split, there was no backup at the standby area. Managed to get a same day FP+ for the Mine Train, various times popped up when I was refreshing, mostly near the start of the party but was able to get some for ~1 PM. Went to Buzz and encountered our longest wait of the day, ~6 minutes and I blame that on the fact that there was a brief downpour that no doubt sent people running towards the indoor rides. by the time we were off Buzz, the rain had stopped and we rode the 7DMT before heading out for the day.
Finally, AK. Arrived around rope drop and easily got on the first parking tram that pulled up. We've usually had to wait for at least the second, if not the third so this was a pleasant surprise. The security area was very well staffed, more than I have seen even on busy days. My niece got her face painted and then we rode the safari and saw most of the animals, including the new baby giraffe. Afterwards, we rode KRR and went up to Rafiki's planet watch to get the photo with Rafiki and do the petting zoo. Stopped in Pandora to use a FP+ for Navi River Journey before heading out to AKL to grab some food at the Mara. The Mara was pretty much empty. I joked that you knew it was a slow day at the Mara because you could actually get ice from the soda machines. The lines to order food were short, most people seemed to walk up and look at the menu before ordering as there was no one behind them (usually you'd have plenty of time in line). The pool area is now closed at AKL so maybe this had something to do with the smaller crowds.
But this past week has definitely felt "quiet" and it's interesting that Disney is worrying about it.
