Seventeen interested

Nine people confirmed. Eight clicked “interested” without choosing a date. The visible total mixes two kinds of reply.

The larger room costs 40 tokens. Cancellation is free until tomorrow noon. The smaller room remains available until then.

Three can attend. Three cannot. Two have not answered. You now have twelve confirmations and two open replies.

Decision basis: More space protects against extra attendance, at a known cost. Keeping the booking past noon gives up its free-cancellation option. Outcome: Only ten people attend. The larger room costs 40 tokens and has spare seats. You could have reviewed the reservation before noon, but this plan kept it. Review: The smaller attendance does not by itself make buying space unreasonable. Inspect whether the uncertainty justified the cost and whether a review could have preserved the same protection.

Decision basis: A clear capacity and real confirmations can support a bounded plan; the remaining demand still needs an answer. Outcome: Ten people arrive and fit comfortably. The two missing attendees had ordinary last-minute changes; you could not know those changes in advance. Review: The fit is useful but not a forecast you proved. Confirmation and a clear limit gave the plan a defensible basis.

Decision basis: Waiting can use up an option even when certainty will never arrive. Outcome: The larger room is taken by another group. Ten attend, so the small room happens to be enough. Review: A harmless ending does not mean doing nothing preserved every option. The reversible reservation was available only during the decision window.

Ten people attend. Two confirmed visitors cancel late. Their later cancellations are not evidence that you could predict them today.

1. Today: seventeen mixed replies, with twelve existing seats. 2. Decision window: the larger room can be reserved. 3. Tomorrow noon: free cancellation ends. 4. Workshop day: two confirmed visitors cancel; ten attend.
