I ended up tracking bookable dates during the last two weeks or so and observed that the earliest available date is always two months from any given date I checked. For example, when on 9/5, the earliest available date was for 11/5, 9/6 for 11/6, 9/9 for 11/9, etc.
On 9/5, I called WM about availabilities in October, and again was told they were fully booked and there was no inventory until 11/5. I asked if they can submit a ticket to inquire about the missing inventory within the next two months, or anything that was preventing owners from booking dates within the next two months, they said they won't do it as there was no discrepancy between the inventory they saw on their end and my end. But I don't really quite believe that the resort was fully booked for every single day within the timeframe, as I saw there were 9 available unit types with multiple types of studios and two bedrooms all had 4-7 units each available for 11/5 when checking on 9/5, but when checking on 9/6, nothing is available for 11/5. Same thing for 11/6, checked on 9/6, 9 types of units were available, but one day later, nothing.
I honestly do not care to book anything anymore, just getting rather annoyed and want to vent. It looks to me that WM just took them offline instead of someone all of a sudden booked them all up at exactly two months out every single day. I mean, maybe there is a good reason to do that, such as for better cancellation terms? Otherwise where could that inventory have gone?"
