Include event free or busy in the description of the event.

I would be helpful and convenient to be able to see if an event free or busy in the event description in OP instead of signing in to google calendar to check.

I was trying to figure out why some booking pages weren't allowing others to book an hour in a day with an all day event I thought was free. 

Others can put events on my calendar or sometimes I don't remember to make sure some period of time is free even though the event is a reminder to me that I will be in a different location, city, conference.
