Our trips do sell out quickly, but there are always cancellations and changes. Once they fill up, we build a waitlist. However, we can’t predict the odds as it depends on those that cancel.
We fill opening via email. It’s not like a deli serving # whatever. We often need to fill a spot quickly and don’t have the luxury of time. The first reply gets a hold for 24 hours to allow time to ask work. If no reply, general members next in bulk. There is no specific order, everyone has an equal chance. All others remain waitlisted and notified again when there’s another opening.
The wait list is really unreliable because most people make other plans. To stop getting notifications, just ask to be removed.
