Arrived Jan 30, 2020 with a group of 11 adults. Second day into trip we spent the day at the side pool. Few of us had a tequila shot and mojito. Simultaneously, 5 of us became very ill. Vomiting, could not stand up, passing out and blacking out. We have no memory of the rest of the day. Only thing I remember is being dragged up the stairs to my hotel room by life guard and other staff member. Thankfully, the members of the group who did not get affected ensured we were cared for. When I woke up, I had hot/cold flashes and vomited bile for the next 10hrs.
