One other note, and it was probably mentioned upthread but it is worth repeating: many of the "better" resort systems (particularly Marriott and Vistana/Starwood) have internal preference periods for most of their deposits. With preference, exchanges are exclusively available to other deposits from the same or a related resort system for a week or two, plus or minus. During that time, most of the high-demand inventory will be taken before a deposit from outside the resort system can "see" the inventory.
DVC's disclosure guide has the usual language about system preference. So, while there is a chance that they negotiated an exception to it, seeing as how Marriott owns II, that's...probably not what happened. We'll know more in a few weeks.
That doesn't mean you can't find some gems. This morning, there is a 3BR at Marriott's resort near
Disneyland Paris in mid-May, and several late July/early August 2BRs at one of Marriott's inland HHI locations. The latter is not oceanfront (and those would be rare as hens teeth in the summer for a non-Marriott exchange) but is very close to DVC's HHI resort, and still better than a sharp stick in the eye. I saw all of those with a non-Marriott week that has very good but not quite top-of-the-line trade power. DVC owners would see at least that much.
The DLRP resort is Elite, and the TDI for that week looks to be about 130, so it would be 340 points. Maybe a little high, but maybe not . The HHI resorts are Premiere, and the TDI is 150, so those would be 230. That's a much better deal than the 337 that DVC-HHI would require in the same time period---if you could even book it at seven months.
