Yes, I have EC, but you don't have to be a member to get the good rates. In fact, I always check rates when I am not logged in as a EC member. If my rate has gone down, I then log in to EC and make a new ressie.
You will get the same rates using the same codes I do. I use Priceless (6600330) and Ent. $20 off coupon (10009123).
I would recommend EC though. Last trip, our luggage was already coming on to the carousel as we arrived. We grabbed it, walked to the garage, picked our car and we were off!
