I've been traveling through Southeast Asia for two months, and something like that never happened to me. To start they charged me 20% more "tax". As if it were not enough, they entered the room, without forcing the lock, and they robbed me. Was the hotel's personal because they cleaned the room and did not force the lock. The manager laughed in my face while he repeated that it was not his staff. A disaster.
The last days we had to put the things that were left in a bag and carry to everywhere. To go out to eat nothing else, of course, things like beach we could not do anymore. We had to deprive ourselves of everything and advance our return. We still do not know how many things they stole from us. It was the worst mistake of my life to have fallen into this cave of thieves.
