I was there 2/8-2/14.
Just got back last night and, well, they already indicated attendance is down at WDW but I thought I'd add a few observations.
It "felt" crowded. We were coming off the tail end of the national cheerleading competitions but to be honest I didn't see as many groups of cheerleaders as I had anticipated - it certainly wasn't overwhelming.
They were all over DHS, MK, and Epcot and only started leaving on 2/12. My flight home was loaded with groups of them.
Genie+, LL, and Virtual Queues are a joke. Seriously. They are hands down without a doubt in my mind the core problem.
Their needless impact on Standby lines is quite visible. Many families I spoke with grudgingly forked over the $$$'s and weren't happy with the results. Tron and Guardians VQ's were often gone within 30 seconds - even when I kept hitting refresh at exactly 7am for Guardians, I got an estimated callback time of 480 minutes or more - often 3 or 4pm, running into the afternoon (1pm) queue.
Did Guardians twice via Virtual Queue and both times we waited in line almost exactly 50 minutes. It seemed for every 50 VQ's they let thru, they let 100 LL's thru. I haven't run the calculations yet to determine if they are selling a proportionate amount of LL's so that the VQ's are almost a consistent 50 minute wait time, but I do know that not having a regular (and unpredictable) standby line makes it easy for them to play the math.
I didn't even bother with G+ or LL. Rather I was flexible with when I wanted to be in the park and was able to take advantage of significantly reduced wait times. (Walked onto ROTR with in the last hour before closing). The only time I went to the MK was for an after-hours party, in which it was sadly the only time you can actually enjoy experiencing attractions at the park. (Make it so miserable, you have to pay extra to have a good experience)
For the last several visits I have found myself spending less time in the parks (except for EPCOT) because of the ridiculous wait times and more time at the resort.
It was amazing to see the parks full of people not actually doing anything. The G+ effect has created this phenomenon where guests are just mulling about not sure of what to do, either because wait times exceed their tolerance to stand in line or because they are all out of other things to do. I especially feel for the families with young ones who planned on doing a whole day at the park. The only way you can do that now without going insane is by paying for G+ and ILL.
Frequent downtime put enormous pressure on other attractions in all parks. If attendance is truly down (and I have no doubt that's the case), wait times are in for a world of hurt when more people are packed into the parks.
Carefully controlled park reservations and G+ sales will ensure that the parks always "feel" crowded even if there are fewer people going. The goal is no longer filling the park, but creating the conditions to extract as much revenue per guest as possible.
Dining - most table serve we went to had more tables empty than occupied and that only seemed to increase the higher up the signature chain we went. I didn't see a single guest in any park gnawing on an $8 Mickey pretzel the entire time I was there.
EPCOT was packed, yet the Festival Kiosks were dead. During peak afternoon there were little to no lines at even the popular Kiosks. There were no lines at all after 5PM. In regards to TS restaurants, I didn't make any ADRS until either day of or 2 days prior. It was amazing to see how availability magically opened up for so many places.
Resorts - lots of empty rooms. Not that I personally checked but derived that from conversations with several CM's onsite.
Deluxe Resorts (non-DVC) were noticeably empty. Values were packed with the cheerleader groups.
It was a disappointing week. Even with the experience we have storm trooping the parks the yield was minimal. Several times we went into MK and just left after an hour or so because Standby times were ridiculous. Oh, and the posted wait times in many cases now seemed to be a bit conservative - I was also running Tour Plans Line WDW app on my phone and it's "Expected Wait Times" were way off. For example, often ROTR would have a posted wait time of 75 minutes and Lines was reporting an expected wait time of 20. We would get in the line and the wait was more like the posted time.
Generally I observed that posted wait times were about 15-25% longer than the actual wait. I don't think there is a greater way to feel miserable than having to wait for a MK or DHS Attraction between 9AM and 3PM.
I feel sorry for the many families we met who were struggling with the logistics and costs of simply being able to do stuff. Their level of frustration was readily apparent.
It's terrible for guest retention. You've got to wonder if they realize that and what their end goal is. Push away AP holders, push away first time guests, push away returning guests. I guess they figure for every one guest that they push away 4 more will take their place.
