With the check-in 11M + 7D booking,
DVC could prevent "walking" reservations with 2 rules:
1. No single reservaiton # may have more than 7 nights (although it could be eventually linked to other #s). This is essentially what MS is telling people they must do to add on more nights after the first 7 night reservation. However, becuase the computer system allows longer reservations, as a practical matter, members are calling back the next day and adding more nights to the first 7 night reservation #. Without a rule (or computer system) change, there is NO risk of not getting the additional nights after you get the first 7.
2. Prohibit cancelling and rebooking the same room category within some period of time (WorldMark has a 48 hour blockout). This stops the cancellation of days 2-7 and then re-booking 2-8 to get around rule 1. With cancellation and rebooking, there was always a slight risk as Member #2 (probably) could have waitlisted for day 2 earlier in the day, thus blocking the rebooking of all days. With rule 2, the risk of losing days 2-7 increases substantially.
So this eliminates the possibility of "walking" a reservation, but does not really help those who do not have enough points to book 7 nights. Under any scenario, those members will be shut out from prime nights such as Thanskgiving, Christmas and NYE.
Eliminating all cancellations will not help these less than 7 night bookers, because members who really want those prime dates will just see booking (and keeping) the extra nights as the de facto increase in points cost. Delaying the right to cancel only keeps those with waitlists on hold for longer, without benefiting the less than 7 night bookers.
Obviously eliminating cancellations entirely hurts many members who currently cancel as part of a normal planning process. Such a rule might actually help commerical renters as their inventory of nonrefundable reservations looks a lot more like the inventory available to DVC members.
Just to be clear, while I beleive these changes would solve the "problem" of "walking" a reservation, I really hope they are not adopted. It would really turn DVC into a standard 7 night timeshare. -- Suzanne
