I'm the kind of person that things that you don't have to sacrifice nature & environment when you wish for great and luxurious vacations. I've been traveling in Mexico for some months now and I found what is seems to me as the perfect blend between luxury and ecology! I just hope more hotel groups think about the importance of nature! Take a look at the sustainable tourism info of the Hacienda Tres Rios Resort in the Riviera Maya, Mexico
Hope u like!
