I was also a member of club mahindra for 2 years. i had paid some 90K but could not take even single day of holiday as the resort are always full. Guess what, once i asked a friend of mine (non-club mahindra member) to check availability, he was given assurance for booking whereas i as member was refused for the same period. Thankfully, i managed to get most of my money back but would request to think ten times befor taking it.
