While I can't speak about "recent" events but my most recent visit of six months ago and probably my 15th one had no similar issues to those you mentioned. On occasion if we arrived early we were checked in and offered to store our bags in the unit until it was ready.

I have never received a key from anyone other than the front desk. Most times we skip the concierge visit altogether.

As far as activities, I have no memories of any cancellations but I assume at some time any could be cancelled.
I have attended the Managers Party every year and never has it been cancelled. I will add that I believe it is usually on a Monday or Tuesday..not Friday
I do not recall any Sunday beach party being offered
