All the ideas seem like they will work but as soon as you are making rules for modifications that are not consistent to all modifications then you are
changing the nature of a FCFS system.
If I book Oct 1 to 8, and I can move it forward all the way to October 15th to 22nd but not to October 16th to 23rd, you have two different rules going on.
The whole FCFS rule applies no matter what and rules can’t be set up to apply differently for the same situation.
Switching dates is switching dates. The only way your process works is if it applies to all bookings.
DVC can’t make rules to prevent one specific type of modification just because people don’t like the outcome at certain times.
If what you are proposing is that any shift in dates, 11 month window or not more than 14 days in the future, requires a cancel and rebook, then that might mesh with the FCFS rule.
But it would have to apply to any and all reservations, not just ones that might be walked.
That’s what I mean by consistent. The biggest thing is DVC has to look at setting booking rules that make sense and ones that they can give a plausible reason as why it was needed to improve the system for the membership.
Having a cancel and rebook or modifications of dates no more than 14 days without a cancel would be hard to explain to the average owner as to why it’s better.
I know your idea is based only to stop or curb walking but the rules have to make sense for all situations. That’s what keeps it in line with the POS.
As I said, DVC has the ability to modify booking procedures but they can’t make rules that don’t apply across the board or aren’t grounded in an attempt to improve the ease in which we book.
If forget about walking for a moment. ask yourself if you think that there are a lot of DVC owners who would like to see a cancel/rebook or limits on being able to change dates of a reservation.
