Dennis: I am helping Raintree Vacation Club Members resolve their problems. Please contact me at firstname.lastname@example.org and I can connect you with someone with Member Services. Based on your note, it appears you may not have a clear understanding of what you bought. There are significant differences between a traditional fee simple timeshare interest in a specific property and a Raintree Vacation Club Membership.
The Raintree Vacation Club purchaser acquires a beneficial trust interest/membership in a particular resort property (in your case, Birch Bay in Washington State). But WHERE your timeshare interest is purchased isn't really important because at the time of purchase, the buyer simultaneously deposits or assigns that beneficial trust interest/membership with Raintree Vacation Club in exchange for a Raintree Vacation Club Membership and the associated usage rights and responsibilities. These include usage rights to all Raintree Vacation Club resort properties in 16 destinations in Mexico, the United States and Canada as well as access to RCI, the world’s largest timeshare exchange company.
So just because your timeshare interests are backed up by real estate at Birch Bay doesn't in any way influence what resort properties you can reserve within the Raintree Vacation Club system. You have equal access to Cabo as the Members whose timeshare interests are backed up by the Cabo properties. All Club Members have pooled all their timeshare interests. It is a lot different than purchasing a timeshare at a particular property -- much more flexibility to go where you want.

The process of first purchasing timeshare interests in a particular property and then assigning those interests to Raintree Vacation Club in exchange for a Club Membership is a common practice that has been reviewed and approved by the agencies that have jurisdiction over timeshare sales. By doing this, the Club is able to pool all the interests of all the Members to provide usage to all the resort properties to all Raintree Vacation Club Members and offer a wide variety of exciting vacation options all Raintree Vacation Club Members can enjoy.
