Forgot to post here, but as an EE picked up on a full-size reservation on May 21st for 6 days. There was an Audi Q3 in the exec aisle, poorly optioned (no keyless start) that I hemmed and hawed on along with the usual Nissans and Hyundais, but there was a BMW X7 in the Premier section with a cracked windshield and I was able to negotiate a $40/day upgrade. Was worth it as the cargo capacity came in handy, as did the ventilated seats for the 110º Vegas weather.
