In the Wyndham Resort Owners Forum http://forums.atozed.com
there is a spreadsheet posted that shows the maintenance fees for Wyndham Resorts from 1994 to 2008.

The MF's are current up to 2008, but most likely they have gone up for 2009. It's not an "official" Wyndham document, but it should give you an idea of the range in MF's for the Wyndham resorts.
