These are refereed to as "shared, or common" areas. The effect on ones dues is that they are DECLARED as "shared, or common" areas.
The pool at Bolder Creek has always been a shared area.
Sturdy Branches, if shared with CC, is now a SHARED area.... BC dues for this should thus go down, shared between CC and BR.
New Restaurant is a SHARED area... Hotel, BC, and CC.
Now - worth noting.... "shared" areas were declared in your original
DVC contract. Be on the lookout for any attempt to unilaterally alter a contract.
