I was at the park today. From Batman, I could see that while the facades next to the load/queue building were all torn down, the load and queue building itself is still untouched, so I figure it's pretty likely it'll remain.
On a side note, mask wearing and social distancing at the park is not great. If you're not vaccinated, I personally wouldn't go. A few valiant employees try to enforce it, but they're in the minority and vastly outnumbered.
When I arrived at 1pm on a Wednesday, the biggest line to get in was for parking, which was pretty backed up. Fortunately, it did keep moving, but still took about 15 minutes to get through. Fortunately, the lines to get into the park were essentially non-existent.
Pro-tip: make use of the mobile ordering. It can also be used for free drink refills (if you have a souvenir mug), and it really saved a lot of time, because we all know what the SFMM food lines are like, and I really didn't want to stand in them just to get a drink refill. If fact, it appeared very few people were using the mobile ordering at all. Since I only used it for drink refills, I don't know if it's as fast for actual food, but part of me says it can't be any slower than standing in those food lines.
Another side note, if you continued membership payments during the pandemic, you can now get a gift card credit at the Membership Services building (in the plaza between the entrances to SFMM and HH). This is apparently very new news, it's only been available for a few days at best. It does have limitations: it can't be used for any sort of online payments or fastlane (as that is done by a third party). But nearly all food and merchandise in the park are covered (select independant vendors may be exempt). I kept up the Diamond Elite payments all this time, and my gift card was for just under $260.
