Anyone here familiar with BVC hotel room bookings?

My husband and I are fairly new with BVC but we are getting VERY FRUSTRATED doing the rooms bookings.

There are so many TnC which are not listed in their contract.

We just found out (the hard way) that we can only:
1) Book max of 2 room nites stay.
2) We cannot book our 2nd holiday until we have utilized the 1st bookings.
Like this, how do we finish the 7 days FREE ROOM STAY Entitlement?

All these Vacation Club membership is a darn RIP OFF.

Can anyone please help LET ME KNOW how I can go about the MULTIPLE ROOM bookings and MULTIPLE VACATION books. Planning our DECEMBER holiday and trying to utilize all 7days in that month.
