I had a fairly dreadful experience on holiday last year. Went to Spain with a group of friends/acquaintancies, ranging from 30-50, including some married couples and several gay men. DH doesn't like going on holidays so it was a chance for me to go in a nice group and have company.
Shortly beforehand, one of the men asked if me and the married woman (also sans husband) I'd arranged to share an apartment in the hotel with would share with another (gay) man. I was reluctant as I only knew him vaguely and it didn't make the room any cheaper, but was pressurised into agreeing. Thought he was quite a nice man though.
On the first night, we all had a good time and some of the group went out clubbing, me and the married woman went back about midnight to our rooms to sleep. IT was incredibly hot and the hotel had no air conditioning so we quickly agreed that neither of us was bothered whether we slept topless.
The apartments were comprised of a bedroom with two twin beds and a living room with a kitchen off, where the man was sleeping on one of 2 sofa beds.
I suffer from back problems and am sensitive to hard beds, this is alleviated by using a mattress topper or similar, so I took the thin mattress of the spare sofa bed from the living room which had no belongings on it.
About 4am, the door to our bedroom burst open followed by the man, ranting and raving and shouting about how I had "taken his mattress". Of course there was another sofa bed with two of his bags on it so I had no idea what he was talking about. But he started shouting that he had to have his mattress back now, he wasn't going to leave the room until he got it and all sorts of stuff about how I had done it deliberately and that was the sort of person I was. He was extremely drunk and would not be pacified or leave the room til I put clothes on. I had to get out of bed, holding the bed sheet in front of me to cover me up and carry the mattress through to the living room. Hotel security then showed up, but he went to the door and told them everything was ok and they went away.
I then tried to go back to sleep, but he burst in another two times during the night, shouting abuse at me. The married woman was also very drunk and slept, or effected to sleep through it.
The next day everyone obviously knew as I slept in and he had spun his version at breakfast. I am proud to say that I confronted him about it at dinner though and told him he was a disgrace. He tried the standing up towering over me shouting "sit down and shut up" thing but I just told him he didn't intimidate me and he was an abusive idiot.
That night, much the same scenario played out, minus the mattress - I made a point of taking a different mattress of the other sofa bed. He still burst into our room and walked about muttering and I could hear him shouting and banging in the living room.
The worst thing was that the living room and our bedroom was connected by a balcony, so even if we shut our door (there was no lock), he could just walk round by the balcony and through the open doors to our room - it was so hot, we literally couldn't breathe without them open.
The next day, I actually felt ill with lack of sleep. There were 4 more nights to go and I pondered getting an earlier flight but in the end I booked different accommodation and left in a taxi, leaving a note for the married woman. None of that group even bothered to text me to see if I was all right.
It cost me a fortune but I have to say the feeling of sheer relief when I settled into the new accommodation was immense, and I enjoyed the rest of my holiday. I also hooked up with two other women from Denmark and from Poland in the same accommodation that I've kept in touch with and met up for another holiday with.
I honestly think I was lucky not to have ended up as one of those deaths where someone "falls" off a hotel balcony (it was 18 stories up)! The man was that angry and enraged. I later found out that although he still lives with his mother although he is in his fifties and apparently holds down a mega well paid job in finance despite having no qualifications - clearly shouting and being enraged has worked for him in life...
