Planning Notes

  • Treat this as the fallback or alternate date if May 1 becomes harder to book.
  • The venue format mirrors the first night, so the same gear and arrival recommendations apply.
  • Check the source page directly before booking because multi-night event weekends can change availability quickly.

What Changes During This Window

These are the reasons this event is worth scheduling around instead of treating it like a generic date label.

Highlight

This duplicate weekend date shows the sanatorium is being run as a two-night investigation block.

Highlight
