Is it advisable to pay membership fee for selling timeshare?

[neku]

Due to hard selling and mental torture I paid large amount for timeshare about a decade ago. In the last few years I have not been able to use the time share due to personal reasons. I was contacted by a travel company and they are asking for a membership fee to sell the unused timeshare. A relative had paid a similar membership fee and no timeshare was sold for more than 1 year 10 months. Is it advisable to pay an additional amount for selling the timeshare, do you know of any frauds?
