I'm reading disturbing messages about some of the resorts. It seems that people are having items (cash, clothing, mp3 players...) taken from their rooms. The most recent posts were concerning the Iberostar and the Reef Resort. Is the hotel-provided safe not good enough anymore? What's going on here? Do I need to put a lock on my suitcase (seriously) and bring an extra lock-box? Can strangers get into the room safe? I've also read posts where people claim to have had their rooms entered while they were gone, though nothing was taken, and it wasn't the maid service. Yikes.
