The agenda says lakeside session, the sky says otherwise, and the group is now standing in a hallway. Weather did not ruin the retreat - the missing plan did.
A rain plan takes about an hour to build and turns bad weather from a cancellation into a room change.
Start with one question to the venue, in writing: which single indoor space holds the whole group at once, and what does it take to set it up? Then walk the agenda and give every outdoor block an indoor twin - same purpose, different room.
Confirm who moves chairs and how much notice the venue needs. A rain plan that depends on furniture nobody agreed to move is a wish, not a plan.
Book outdoor dreams with an indoor twin for every block. Then weather is a detail, not a verdict.
