congrats on the change of plans!! you will find so much on here about the different resorts in mexico. i know this site has helped me. we are looking for something not to expensive from calgary and i think we found a place that is classy but not to pricey. it,s called the grand palladuim in the mayan. i,m actually going to check it out on the 14th and maybe a few others while i'm in mexico..
best of luck with your decision and happy planning!!
