Have to remember they have this "never admit a mistake" mindset. When Trump mistakenly included a state in a vague "watch out for hurricane message", he double downed to the point of drawing a fake storm track in sharpie to claim he was really really right.

Every normal little flub that is perfectly understandable and forgettable they have to make so much worse by failing to let it go.

They pre-announced it, then they were too prideful to admit that they messed up by not actually asking for availability beforehand. Then it wasn't available, and they instead booked the landscaping place to be able to say “t-t-t-that w-was always the p-p-p-p-plan!!!!!1111 We said 4 seasons! Not hotel! Nu-uh!“

The landscaper/owner had to have known and been quick enough to facilitate the event.

I imagine the guy got a call, someone explained what they wanted to do and went "oh this is going to be hilarious" and just said yes to everything.
