That is a pretty tough property to get for a number of reasons. First...it's small ...only 200 rooms or so...second...you are going pretty close to peak season...and last...everyone and their mothers' try to book awards there.
I have been lucky and gotten awards there on 2 occasions. Once it was actually available...and the other time..I had to call a fairly high ranking friend that I have at Marriott. These were both 7 night stays.
