Cancellations Filters with BaseCamp: Cancellation filters allow you to set up to 5 individual filters to show you just sites and dates you might be interested in at specific campgrounds. You can setup a filter for a specific regions and/or specific campgrounds. Select your equipment size, any hookups required, on/off water if you desire, and minimum number of nights. You can then select a date range or specify midweek or weekends. For midweek you can select individual time periods.
