Would be good when making a booking for a guest, that you could tick  box somewhere in the booking window that allows you do get their booking reminder. I know that you can set up to get notifications but would be good to just get select ones. For example a friend or a person of interest is booking in advance and if you could tick a box to get booking reminder notification, it would go to the address that is currently logged in with, then it allows you to check in with booking prior to dining, as sometimes you overlook a certain booking when reviewing the dairy in advance or not working on the night the bookings occurs etc.
