If you're looking for a better way to prevent double booking, consider importing calendars to your Homeaway calendar. This enables you to have a single-calendar view of all your reservations, seasonal events, holidays and more. It also helps you see opportunities to adjust your rates to make more money. On HomeAway, you can import up to 5 calendars from other websites that support the iCal format such as Google. Get the step-by-step instructions on how to import calendars here.
