On Tuesday night when I arrived, I was checking in with the security man and I was not on any of his lists, then he told me that I appeared as if I had already checked in when in fact I had just arrived.
then he sent me to two different rooms which were both already full! And in the end, he ended up leaving me in a shared room with 8 people, regardless of the fact that I had paid for a room with only 4 people.
