Asking for "flexibility"

Email 11/18:

A,

My Dad and P will be coming out the weekend of March 9th through the 12th, 2012 to see S and T.  I am not sure how this falls in our visitation calendar.  I wanted to give you as much notice as possible in case you were planning anything.  They have bought airline tickets.  If this doesn't fall on my scheduled visitation, I will take the March 9th through the 18th for my vacation week.  And at some point during that week I will be taking to Long Beach to see my Mom.
