FYI - I just CNX'd my Embassy/La Vista reservations for 20-24 July. So jump in and grab those as desired, but you may wanna note this cautionary tale...
I first attempted to reserve the room when the convention block opened last summer. As described elsewhere, this process was fraught with trouble, which (hopefully) does not need to be rehashed here. I reserved a room available for three of the four desired nights...or so I thought. I called them in the Spring, hoping to add the fourth night and they had no record of my reservation and no availability. So I made alternative arrangements: Initial hack was the nearby Hampton, in the past a lovely option; but their sole available room was outrageously expensive. Fortunately, our relatives in town were willing to host us, so I CNX'd the Hampton. All good.
But today, we got an upgrade offer from Embassy Suites, regarding that first, 'lost' reservation, which somehow magically re-materialized. After a difficult telephone experience requiring multiple inputs of various personal ID data (while holding a confirmation number!), garbled audio, an apparent language barrier and inconsistent descriptions of the reservation, my BS-meter was pegged and I CNX'd it.
Otherwise - am still looking forward to the fun part...!
