Well they have posted their September AP rates but I am very disappointed. I can get better rates buying from a travel site.
Without looking at the rates that you saw for myself (my AP expired in October, so I am not sure if I can even still access the AP portion of the DLR site), I suspect that what they are doing is what they did last year - they are waiting to see how many people book at the higher rates before they release the
really good AP rates.
Are the rates you see for, say, PPH and DLH well over $220 per night right now? If so, then I
think that what they did was just post what the lowest available rates for AP holders would be if you were to book
at this time...but not the actual 'AP rate' yet, if that makes sense! In other words, the rates I am guessing are the ones you saw for September are most likely merely the regular rack rate minus the regular AP discount (is it 10%?) that you could get 365 days a year. But, when it gets closer to September - like probably sometime in July or August - they will suddenly change some of the rates currently shown for September to the famous 'AP rates,' like AP9 or AP10 or whatever it would be by now. Those rates will be the ones that are under $200 per night for PPH and DLH (though they may try to hike up the DLH rates a tad because of all the stuff they are remodeling and overhauling there). I would guess that PPH would ultimately be in the range of $129 - $159, and DLH would be about $50 higher than that, and, of course, GCH will be much higher, somewhere well over $200+ range for the AP rate.
So I would still go ahead and book somewhere where you don't have to pay anything up front - just to have a reservation in place. Keep checking the AP calendar all the way until August and see if you can catch some lower rates, and if you do, jump on it right away and cancel the other reservation. Remember, the really good AP rates for October last year did not come out until mid-September! They wanted to wait as long as possible.
Plus, this year they have the get 5 nights for the price of 3 again, and that ends in September, I think, so they will probably wait a bit before offering other highly discounted rooms. Just a guess...I could be totally wrong...
