So the new Host Tools includes Rule-Sets, which seems to give hosts a lot more flexibility with pricing and availability settings.
You can set custom discounts, length of stay rules, and check-in and check-out restrictions, and make them customized to specific dates on your calendar.
I know a lot of people have asked about being able to set days the people cannot check-in AND days that people cannot check-out.
And also to have custom check-in and check-out restrictions for specific dates/months.
The new Rule Sets seems to offer that. (Along with a lot more custom pricing and such.)
Has anyone tried setting them up yet?
