I was out with friends the other night and told them we were going to Playa Del Carmen soon. (Sandos Playacar) Both of my friends said when they went to an all inclusivein Mexico(different ones) that they each got very sick and they did not drink the water at all. Neither of them knew how they got sick but wondered if the ice in the mixed drinks was the culprit. Both of them said they got sick the day they were leaving and it was very difficult to get on the airplane. Any advice out there? I am a little worried.
