Revisiting this topic as I had to search online to confirm the stupidity of the Disney reservation system.
Background: I'm a DVC member, and I booked a studio for 6 nights at the Poly at the 11 month mark. My in-laws didn't originally want to go, but had a change of heart 2 months out from our vacation. Unfortunately, Poly's DVC rooms (on points) are 100% booked for the time we are there. No big deal because I'm willing to book them a cash room, which has availability.
Problem: The in-laws specifically want to stay 4 nights, Monday (check in) - Friday (check out); however, I can't book a cash room for just the 4 nights my in-laws want to stay. I can book them Monday (check in) - Thursday (check out) and I can book them Wednesday (check in) - Saturday (check out). Yet somehow the reservation system won't allow me to book their desired 4 nights despite the Poly clearly having availability with overlapping nights. This is absolutely infuriating. I'm trying to give Disney money for a 4 night stay at a $600+ a night hotel, and yet Disney is essentially telling me my money is no good and I either have to do a 3 night stay or a 5+ night stay, because Disney stands to make more money by withholding that last night for another family who is more likely to stay a few extra nights. So annoying. And yet they wonder why people have soured on Disney in the past 5-10 years!
That concludes my Ted Talk.
