Don't know the answer to your first question. Not sure if you are asking how much will be available to members at opening or how much of the entire resort will be ready for occupancy at that time. If it's the former, the member inventory will include all sold points plus a little more to make sure sales can take place. (Can't sell more points than are in member inventory).
More inventory will be added to the "members' pot" as sales are made.
Any inventory ready for occupancy but not declared into the condominium (members' pot) will be available to the general public via CRO. Proceeds less a percentage to CRO) go to the Developer.
