My husband and I will be taking a family vacation to Cancun with our 2 daughters, ages 21 and 23 in May or early June. We have never been there and need some suggestions. I've read that the JW is more upscale and would probably be a better choice given our girls' ages. Any thoughts on this? We also need advice on places to explore, shopping, dining, etc. We are platinum members and will be using our points to stay free. Yay!! A lot of people rave about Club 91....is it possible to be upgraded free of charge even though we are using points? Or are the free platinum upgrades only for PAID stays? We are all looking forward to it........it's going to be an awesome vacation!
