I went to MK on the 40th.
It was an absolute gong show.
I left the resort at super earthy by bus. Many other obviously had the same plan. Problem was Disney did have transport running from the TTC early enough for these folks so there were many people walking on the roadways to the MK.
Merchandise was gone within the first 30 and landed on eBay by the 45 minute mark as Disney didn’t have any quantity rules in place. The specialty items were incredibly limited (they made about 45 anniversary cupcakes

) and the lines for limited edition pins etc were unbelievable, as they always are.
All that to say Disney must have learned from that debacle. I expect the actual 50th to be absolutely insane at MK - but hopefully better managed.
I came across this photo on the internet a few weeks after my trip. That’s my blonde nugget in the blue shirt. I was just inside the ticket gate area. The crowd behind us was enormous. Needless to say it wasn’t a great experience and I left for EPCOT by 11am.
If you search back to threads from the 40th you’ll see I’m not the only one who felt this way.
Not to mention the opinion of The Dis podcasters.....
