Melia has reduced the number of properties that I signed up for from 9 to 5 properties, am I still obligated to see this contract through?

I own weeks at Wimpen Sueno Azul which is now called Ona Sueno Azul. I originally bought from Wimpey back in 1990ish and wondered if under recent changes in EEC rules whether I can claim any fees back and also how I go about selling these weeks. Thanks.

Whilst staying at a Heritage Resort in Spain, we were approached by their manager to see if we wanted to dispose of our timeshare and offered a way to do so. It involved paying a lump sum and in return, they took our timeshare (2 wks in Tenerife) so we had no further responsibility and gave us a 3 year introductory membership into the Heritage Resort Club with the promise of a holiday each year at a one of their resorts and at the end of the 3 years we can walk away knowing that we have no further responsibility to our timeshare and no requirement to join their club. I am concerned this may be a scam. Do you have any thoughts on this?

Is the Timeshare Investigation Board legit?
