I would call and put in the request now so they have it on record before you get there. If the request is in the computer they will have that info in advance when assigning rooms. We booked our two rooms for Aug. back in Oct and we asked for connecting rooms then and we were given guaranteed connecting rooms because of the classification of room we booked through AAA. I was told at the time that a standard view would not guarantee connecting rooms. We booked garden view rooms with an AAA discount and it is a guarantee, as I was told. We have done it this way for years now and have always had connecting rooms.
We requested and got connecting rooms during President's week. I think if you choose both rooms to be 2 queens, your chances are better. I faxed in about 6 days before.
