There are about 3 times a year that my area is in high demand for lodging. On those weekends I would really like to require a two night stay because I know someone will come along and want both nights. But I want to be able to offer one night stays the rest of the time. I currently have someone asking to book a single night on one of these high demand weekends. Can I actually require a two night stay that weekend even though my calendar isn't set that way? In hindsight, I should (and will) change my description to list the weekends where two night stays are mandatory, but my issue is current... I don't want to be penalized for declining her request. I also don't want to appear to be a jerk. Am I just out of luck this time?
