Hi Tahoe,
Here is more information on this:
Wyndham Resort Development Corporation
The Exchange Network
EXCHANGE PLUS
Wyndham Resorts Development Corporation ("WRDC"), through The Exchange Network (hereinafter referred to as TEN), offers the Exchange Plus Program, which allows WorldMark owners who own other qualified timeshare week(s) the option to exchange their other week(s) through TEN and receive Trade Credits to be used in the WorldMark Resorts system. WRDC intends to continue this program into the future. However, the continuation is at the sole discretion of WRDC, and may be modified or terminated at any time without prior notice; except that weeks accepted for exchange before such modification or termination will be honored under the terms and conditions in effect when the week(s) were accepted.
Exchange of Qualified Timeshare Week(s) Will be Considered Under the Following Conditions:
WORLDMARK OWNERSHIP
The owner of the exchange week is an owner in good standing with both WorldMark, The Club and RCI. RCI membership must be an individual RCI membership, not a corporate or club membership, and must be paid through the date of the exchanged week.
DURATION
Any exchange week assigned by this application is for a one-time exchange and does not represent any permanent conveyance of ownership. Only by submitting a new Exchange Plus Application will subsequent weeks be considered for exchange. Acceptance of any week will be at the sole discretion of WRDC.
NUMBER OF TRANSACTIONS
Program is limited to four (4) exchange week transactions per calendar year.
VERIFICATION
Week(s) must be deposited into and verified by RCI before any Trade Credits will be awarded (up to 4 weeks from request date). The exchange week must be owned by applicant as third party weeks will not be accepted.
ASSURANCE OF AVAILABILITY
Owner shall not withdraw or trade the exchange week to another entity during the period designated for use by TEN. If the week is sold after the application has been accepted, the application shall be disclosed to the purchaser with the disclaimer that purchaser doesn’t have the right to occupy the exchanged week, and the sale shall be subject to TEN’s right to use.
RESPONSIBILITY OF CHARGES AND ASSESSMENTS
Charges and assessments on the exchange week shall be the responsibility of the owner and shall be kept current through the period designated for use by TEN.
In Consideration for Exchange Week(s), Owner will be Granted Trade Credits Under the Following Conditions:
NATURE OF INTEREST
The right to use Trade Credits is an exchange usage right and does not constitute any interest in WorldMark Vacation Credits or in WorldMark, The Club.
TRADE CREDITS FOR USE OF WORLDMARK UNITS
The exchange usage will be signified in the form of credits referred to as Trade Credits. The number of Trade Credits awarded will be in accordance with the grid shown on the reserve side of this form. Trade Credits may be combined with regular WorldMark Vacation Credits in making a reservation and used in accordance to rules and guidelines of the Club.
TIME LIMIT FOR MAKING A WORLDMARK RESERVATION
Reservations using Trade Credits must be booked within twelve (12) months of the date of the week exchanged.
EXCHANGE FEE
There is a $129.00 fee for each week exchanged, and credit card payment must accompany this application. If the exchange request is denied for any reason, the fee will not be charged.
HOUSEKEEPING FEE Owner shall receive one free housekeeping credit for each qualified week accepted for exchange.
As I currently own 3 weeks at a Cabo weeks only resort, I am interested in Worldmark points. I just learned about Exchange Plus program at Worldmark. How does it work? Is it a good way to exchange a week for points? Is it a permanent exchange of a week for points or just a one time deal?
I would still advise reading that FAQ on WMO, for it has important info that nobody has duplicated here directly so far.
