Now that I have Airbnb and VRBO traction on multiple vacation properties I would like to explore creating a direct booking website for family, friends, and repeat guests to book without all the platform fees.What are recommendations on website service that allows for (1) multiple properties (2) running transactions (3) synced calendars?
