You seem to think that those "upgrading" are harming the current system. That is far from the case. I have upgraded through II using a 1BR and studio units in to 2BR units. However these were far from upgrades over all. Sure we got larger units, but we had to sacrifice some things. Trading a peak week for an off peak travel time. Traveling on short notice. Just because one is upgrading in unit size doesn't mean the trade isn't equal overall.
We are ultimatly absorbing inventory that other people don't want or can not use. In that I think we are performing a service to the overall system. Full resorts means more money for the developers, HOAs and II.
Quite the contrary...I agree with you completely. We are indeed absorbing inventory others would not want or use...if you look above I am quite happy with what I have been able to get. That said, I think you overstate the "service" we are providing to the system. I have garnered several unequal trades, a point system might work as a better equalizer by providing more flexibility but ultimately less ability to "upgrade." As you can see from my earlier posts...it's just a tradeoff - one I am on the fence about as I have been happy thus far.
