I've just read three TripAdvisor reviews in a row from people who booked their stay at Azul Beach and were moved to Azul Sensatori when they arrived due to "overbooking". How can that happen? If all guests prepay (like I have for my trip in April), why would they sell more rooms than they have available. And what tips can anyone offer me so I can increase my chances of getting a room? I've already stayed at Azul Beach , and have seen the Sensatori and would be at all happy about having to switch.
