Watch out for all the hidden charges.  We were quoted a one-week estimate of $276 for a compact.  The charge to upgrade to a mid-sized (which was a small 4-door), was only $84.  But the additional charges and taxes for the week were $398!
"Optional" insurance (not optional for us):  $202
"Facility charge":  $10
"Tourism Surcharge":  $10.32
APCONRECFEE (whatever that it):  $55.47
State Tax:  $34.31

The car was fine (a newer Kia) but had very little room for luggage.
Signage was very unclear at the drop-off and pick-up, but the people were friendly enough.

I might use them again, but triple check all the hidden costs and fees before you think you're getting a deal.
