Unfortunately the BTB still wants the hotel tax on the complimentary week.
You really should be careful of what you post, you may be taking food off of people's tables with wrong advice.
Perhaps "timeshare promotion", not "scam". It doesn't seem logical that Grand Colony and Banyan Bay (one of the finest developments on the island) have a need to scam folks. It does make sense to give away free weeks, so they can see you again and give you a test run, next year.
Remember nothing ventured, nothing gained. Don't feel the need to be overzealous and warn others of what YOU may be afraid of.
