Will Calendar Notes Affect Instant Book Availability?
No! Instant Book uses a conflict checker to verify when a date, time and room are available, and thus requires a start and end time on events, as well as a room. Since calendar notes do not have times or rooms associated with them, they will not block the calendar off from being booked. Further, bookings that are created without any timeframe or with just a start time (no end time) will also not be identified as a conflict.
