The two accounts have different numbers.
Lisa:
Those of us who had RCI with WM before the Portal was created have two RCI account numbers.
My old/regular RCI account begins with 2281xxxxx. I currently only log in once in awhile to see Extra Vacations/Last Calls. I don't have another timeshare, so I can't see any Exchange information with this account.
My WM Portal RCI number begins with 9Wxxxxxxx.
If I were to stop paying the annual fee, both would be closed (I won't be able to log in to either account.)
