I think your wrong to remove that date option. You should have kept the date, made people aware the bunkhouse would not be available for that weekend, reset the poll and let everyone vote again with the end date of the poll the same.

THAT would have been a fair way of doing it. What you have effectively done is remove the dates in favour of the few people who would have wanted to use the bunkhouse. You have not taken into consideration the reason why that date had the most votes.
