Hi,
This is my first post to the "insiders"!
We would like to book three different Marriott hotels in May 2016.
One in Las Vegas, Monterey and San Francisco California!
The month of May has not opened up yet. However, how does the point
system really work? Is it best to book way ahead, do the points drop?
Any information would be so appreciated and thanks so much! 
Natalie
