Spa/resort for ladies in Cancun?

Hi everyone! My sister and I have agreed to go on a girlie holiday together , and we are really looking forward to spending a nice, two week long holiday in Cancun in Mexico this summer. We have heard so much about it, and are sure it will be lovely! But we are still looking for a spa resort which would be suitable for the two of us. Any suggestions?

There are many spa resorts in Cancun, and it will be difficult to tell in advance which is the best of course. We stayed at the JW Marriott Cancun Resort & Spa during our trip to Cancun last years and both me and my husband loved it!! I really felt like a Queen whilst there and could certainly recommend it. But then, I didn't try any other!
