I'm leaving in two weeks and am also renting from thrifty. I'm just hoping that buttercups experience was an aberation. It seems that regardless of the area of service at any place, whether it is food, rides, hotels, air travel, etc. there are bound to be some people that have bad experiences (well, with air travel, it seems to be the norm). I would like to believe that there are also people out there who have used Thrifty and had no complaints either.
Plus, I don't have high expectations for their service, as my main reason for using them is cost. I'm willing to trade excellent service for lower costs. Just my preference.
I get back on Nov. 16th. If you're not leaving until after then, I'll let you know how my experience was. If you're leaving before that, good luck and enjoy your trip!
