I am not suggesting that the regional TDI number carries more trading weight than any of the other factors. It is what it is. I'm sure it matters, but how much I don’t know. I can only speak to the fact that the overall TDI number assigned to the various regions for a certainty has something to do with some combination of overall demand, supply, and occupancy for that specific region.
As to the Boston and New York examples mentioned, while I would agree that in general those cities can have high demand times, maybe II’s regional demand rankings also have something to do with timeshare demand for those areas…not just hotel demand? I don’t know. And how many timeshare owners want to take their families to Boston and New York city? Those locations and choices seem more couple oriented, not family oriented.
More specifically money talks and I think it can help shed some light on the Boston / New York value question (as it relates to the timeshare world). You can buy Platinum season Marriott’s Custom House weeks for $1,000 and the timeshare options for New York City are pretty meager as well. Heck, Manhattan Club appears to have been guilty of criminal fraud.
If those places are in such high demand and II’s number is so wrong then why doesn’t a Boston Custom House platinum week cost one $10+k like they would have to pay in Marco Island, Virginia Beach, or even the Marriott’s in Aruba, Hilton Head, Myrtle Beach, or Hawaii? Okay they are 1BR units, but if Boston was in such high demand and had any real value wouldn't they logically sell for more?
While I am sure there are exceptions that can be debated, to me it seems that about 95+% of the regional overall TDI rankings I see listed in II seem completely logical.
