have you any experience of Fullbrook Associates or Proactive Solicitors with regard to timeshare termination

Seasons Holidays plc who own Slaley Hall Lodges Ltd have written to Timeshare owners at Slaley Hall informing them that they are calling for a Special General Meeting to wind up the Owners Club from 30/12/2021.
As they, Seasons plc, claim to own 80% of available weeks this apparently allows them to call the SGM and to have the resolution passed they need 75% of the vote. Therefore the vote is already a foregone conclusion.
What rights if any do the individual owners have?
I’m sure other owners will have raised questions but any advice you can provide would be greatly appreciated.

We want to get rid of our Sheraton vistana resort timeshare in Florida. Been in contact with sell my time share company based there in Florida, they will then advertise it for sale at a cost of $1998. That includes all finalising documents and transfer fees etc. Does not guarantee sale. Is this my best option to relinquish my ownership? I just want to be rid of it and stop paying fees when I’m not able to use it. Other companies here in UK are able to do it but don’t give an exact price of what it would cost.

I’m contacted by a company named Euros Eurostar who want to buy our 2 weeks timeshare at Chayofa, Tenerife Island.
Is it possible to have a transaction through your company in case it is possible?
Thank you very much
