Love Villa Del Palmar--stay every year and no problems. Mexican people are great and only timeshare people are aggressive trying to make a living!!
Americans can be too sensitive to aggressive selling and if they are should not attend timeshare presentations. You can cancel for 7 days based on CA laws since this company is a US-based company.
We love the people selling items on the beach--my wife buys at least 20 bracelets every year as gifts for friends back in Michigan. Everyone we talk to at the pool are VERY HAPPY with VDP organization and staff.
