Thanks! I tried that but I'm an annual pass holder and it's not discounting the rate when I try online - it's just coming up with the same rate whether I log in as a pass holder or not. So I'm thinking I need to call them instead?
I don't know whether it's the same for AP holders, but when I first used my AA membership card I phoned and they said to just show the reception staff the card when booking in and they would take care of the discount at the time!
We only booked a couple of weeks ago for a late July stay and having stalked the price for months it was well below the best price Id seen on other sites.
If there are no Annual pass rates showing they might not have been release yet for your dates.
When are you looking to stay there? It may be that AP rates have not been released or are not available for that time. You can book online and then call and have them apply the discount if AP rates are released.
