Last June, I called 1 week before our trip to see if by chance there was anything open, because we decided to stay an extra night. Got a LV studio, so I would venture to call.....
We were waitlisted last August for a 1Bdrm LV up to 7 days prior. After that I called every day. Two days before our trip we got it! Keep calling!! I plan to do the very same for our upcoming trip
