If you book day by day, then call November 11th (they go by the "check out" date). I would suggest doing that. If you wait to do it all at once, your top choice may already be snagged.
You'll have to call each day (except MS is not open on weekends) until the 18th. Also, 11/11 is Veterans Day, so you may want to check with MS to make sure they are open.
