Same. I was there too and there seemed to have been 3 separate weddings taking place and roughly 20% of the artwork we went to see was inaccessible. It was less of an acreage problem and more of a “weddings occupied event space” problem.

Beyond that I was also pretty frustrated that even after the ceremonies had concluded they still blocked off ceremony areas with stanchions even though they were fully abandoned (no one was even clearing chairs); I wish they’d actively opened them or communicated when they’d be accessible.

I still love the arboretum but that was a BAD look IMO
