I have 10 rental properties.
I book primarily with Airbnb, secondary sites are VRBO and Streamline VRS (which provides a booking link on my company website).
I use iCal links to sync all the calenders
The issues I encounter are:
1) Reservations arriving through iCal links, arrive as 'blocks' not as real reservations - this is problematic because: A) blocks do not trigger notifications so I must manually switch the block to a reservation to receive notifications
B) Most importantly, a reservation arriving as a block, blocks the whole day, that is an issue for days of check in and check out. i.e. if a guest is checking out at 11AM there's no reason why a whole day should be blocked off.
2) Often the dates will be misaligned. Often times -yes its inconsistent - an ical block shows up and the check in date is one day early and the the check out date is one day early.
3) On some occasions the ical blocks arrive as 2 separate reservations i.e. Jon Johny 1/20/17-1/22/17 Jon Johny 1/23/17-1/24/17.
At the moment my system is working at %65 capacity but I'm scared of double booking so I spend a lot of time double checking my calendars not to forget about the extra stress that causes.
What I want is a proper booking calendar which takes reservations from multiple sources and does so smoothly so I don't have to worry about double booking. As a bonus, notifications would also be nice.
