Yup, I am aware of the business relationship and have posted about it in the past. Disney owns just the land which is leased to Tishman and MetLife, under a long term lease; I don't think many of us will still be around for the end of the lease, which runs until about 2089.
To clarify what I posted, my thoughts about the "Good Neighbor" properties concerned their perks, many of which have not been in place all that long. In this climate, I believe that Disney will try to do whatever it has to to retain their share of the accommodations market.
