It's been down for a about 10 days. I called them and sent three e-mails too. No response to the e-mails, and during the call I was told they'd "look into the matter."
Same problem here. At first I thought it was just my stupid computer with the problem. I must have tried over ten days ago to get into that AP hotel availability calendar to look at some prices for different dates at the various hotels and I got the same 'System Error....please try again later.' When I did try again later, I got the same message. And every time I checked since then it has said the same thing.
Finally, when it came time to switch my GCH reservation to the PPH, I especially wanted to see the AP calendar BEFORE I called DLR Reservations and made the downgrade, because sometimes the rates on the calendar are
different than what they give you on the phone for the same dates. Like when I first made my GCH reservation, the AP calendar quoted a
higher rate per night for the dates I wanted than what the CM on the phone quoted me as being available, which worked in my favor, but sometimes it can work the opposite way - to one's disadvantage - and the calendar actually shows a
lower rate than what the CMs quote you!! I couldn't access the calendar, so I had to just call Reservations and hope they were giving me the lowest price available for PPH. I mentioned to the CM that the AP calendar was down, and she seemed disinterested!
The last time I was able to access the AP calendar, I had been wondering why there still seemed to be
so much availability showing on the calendar for next month, at all three hotels (with the exception of New Year's Eve). Maybe they had to take it down to totally revise it and/or re-price some rooms, and then it turned into a bigger undertaking than they had planned.
