Adriana,
I suspect they are ROFRing properties where they don't have good representation in the Trust -- Waiohai is definitely not well represented -- and it also represents a good point value for the Trust. Kauai Beach Club is also not well represented in the Trust, but is better than Waiohai.
Over time, we may probably figure out a rough formula, such as the contract price must be more than [25%] of the equivalent value of the Trust Points to pass ROFR.
So, if a Waiohai Island View is worth 4,225 points to the Trust, when deposited, we know Marriott can sell approx $42,000 more of Trust Points if they ROFR the week and deposit it to the Trust.
If 25% is the right variable (it's a guess, it actually may be lower because they have alot of inventory still to sell and may only ROFR the really good deals), then your sale price must be more than $10,500, or they will ROFR it.
Out of curiousity, how much were the contract prices for the Waiohai and the Kauai Beach Club?
Thanks and good luck!
