Thanks for bringing up the linked calendars! For me, an even better solution would be to make the linked calendar entry "editable".

My airbnb bookings are linked to my iphone calendar. Each booking automatically gets its own entry in my calendar, but the entries aren't changeable. My "fix" is to create a 2nd entry, with the info that I want, rather than the info airbnb provides. (Seriously, why would I need to have a booking confirmation number in my calendar?!?)

Things I add to my entry are:

1) The names of all the guests, not just the name of the account holder who did the booking.

2) What time the guests will be arriving. (I usually get this info from the guests, then add it myself.)

3) The guests preferred contact info.

If it's possible to make the linked calendar editable, viola, simple fix! 

Thanks.
