Kenya. Booked into a 5* hotel on the beach. Hotel itself lovely, but room was terrible. Threadbare stained carpet, stained/torn curtains, often no running water, and regular power cuts (basically entire block tripping off constantly throughout the day). Sometimes no water to flush the toilet. Rarely any hot water at all. We complained daily to be told "sorry, but hotel full, no rooms to move to". Then we saw the other block, which had been refurbished - lovely plush carpets, new fluffy towels, and they had no problems with water nor power. Basically, we were stuck in the old block that hadn't been renovated but paying the same for those allocated to the new block that had. Court case for compensation from Thomson and we got all our money back!
The Gambia. Thomson again! Hotel being renovated. Went into our room for the first time. Dust everywhere, every surface, even on the bed. Went to open the balcony windows and it just fell out - hadn't been fixed in. Electrical switches sockets hanging off the wall. Heard a loud bang from outside and the people next door had opened their room door and it had just fallen off - only 1 screw had been put in each hinge that couldn't hold the weight of the door! There were workmen everywhere, trailing power leads across corridors and stairways. The place was clearly unsafe and unfit for habitation. Thomson rep useless. Court case again, full refund as compensation!
Turkey. Supposedly 5* hotel in Kusadasi - another flea pit, with oddments of carpets on the corridors (not fixed down), breakfast was literally just a plate of stale bread rolls and a dish of boiled eggs - nothing else! No cereals etc. Got ripped off when changing money at reception - handed the guy some UK notes and he just handed back some Turkish lira from a tin box, no receipt, not even worked it out by a calculator, we counted it, and there was probably half of what we expected it to be, so we asked what exchange rate he'd used, and he just got the box out and gave us a few more notes, still pretended not to understand when we asked for exchange rate and a receipt. There was no safe in the room, so Rep told us to ask for a brown envelope from reception to seal and sign across the tape and they'd put it in their safe. We did. When we came to ask for it back, it was obvious the tape had been broken and the envelope had been torn to open it - passports and driving licences were there, but cash had gone - again, receptionist pretended not to understand when we complained. Rep useless and wouldn't help us complain. Unsurprising, it was Thomson again, and again, court case, and we got about a 50% refund as compensation.
