You need a lawyer to review the scheme documents. It’s probably $1000 Usd per month for life. The slimiest tactic was after checkout we were in a rush to get to the airport and as we head to the van cab (note that from the airport that would cost $50 for two in a van, to the airport it’s $11), we are told by saleswoman if we give palace $250 we will get some incredible future credit. No thanks.
If I considered anything a scheme and especially if I was being pressured, I wouldn't be looking to join. There are too many other places in Coz to stay. If it works like a timeshare, I would learn everything you can about how it works, how to maximize the benefits, and not just rely on what they tell you.
