This has nothing to do with leverage. Contractually, whatever booking benefit
DVC/DVD extends to you - they must extend to all blue card members. Maybe DVD would claim this 'benefit' is available to all new blue card members - but based on the recent complaining I heard, that didn't seem to be the case.
See, they gave you not just some random week, but one of most highly desirable weeks of the year - a week that many others, even at their 11 month booking window were not able to book this year because of overwhelming demand. And you 'booked' it with essentially 5 and a half months of lead time. Impossible under any other circumstance.
I gotta wonder if DVD is routinely keeping some rooms out of DVC inventory during certain times of the year for direct sales of a certain point size and up. There definitely was some funny business going on this year with booking certain resorts during the 50th and Christmas.
Then again, maybe this scenario is only possible because much of RIV is still unsold.
