All,
I consider the attached file a little bit of a Rosetta Stone regarding II's trading power. Although it is designed for trading Marriott points into other systems, I believe it helps us think about how II views the relative trade power of different deposits.
Per the attached, a 3BR in a TDI 140-150 is worth 6,000 points -- well more than the 4,500 needed to match against a 2BR in the same TDI. There are 3BR Grande Vista Platinums that can be booked in a TDI 140-150 week.
Additionally a 3BR in a TDI 115-135 is worth 5,000 points -- again more than needed to match against a prime 2BR deposit. There are 3BR Grande Vista Golds that can be booked in a TDI 115-135 week.
This supports the real-world experience that Puck, WindJE and others have stated about the power of the 3BR Grande Vista deposit. And why Puck's 3BR Grande Vista matched before his 2BR Waiohai when chasing Mountainside.
Orlando does have 140-150 TDI weeks, so it is conceivable to get that fully powered deposit. Even locking off the Studio gets you 4,500 (for the 2BR) and 2,250 (for the Studio). Thats a lot of trade power.
This doesn't provide any clarity around the relative desirability (or scarcity) of Orlando versus Las Vegas and hard to tell which would have more power in the inner workings of II.
But this is a reasonable surrogate, in my view.
Best,
Greg
