I rent from this God awful company about 300 days/ year. Has anyone else had a hard time using anything they give away for free? Last year I had about 5 free weekends that went unused because they were "blacked out." This year, I am trying to get a car for a weekend and it says it too has been "blacked out." I am beginning to think they give away a lot of free weekends and then black out all weekends rendering the coupons worthless. I have had other troubles with Avis (especially in Harrisburg, PA) but I won't go into all of that. This is just one more reason for me to move my business to Hertz. If anyone knows what the calender looks like for blackout dates could they please share it? I called Avis First(misnomer) and they could not give me dates. All I want to do is use these certificates I earned!
