Consistently the best code for me has been the AAA code (listed on mousesavers). I have been checking since I first booked last year (May or so) for my upcoming trip April30/May11. It has pretty much stayed too high to give up my good rate with Dollar but in the last week or so, rates have steadily dropped making the price comparable with Dollar. Love the Emerald Aisle and would hate to give that up. Are you using one of the coupons from the website along with the discount? That will bring it down even more. Good Luck!!
