Booked with travel up. Arrived at our booked hotel at 3am and they had no record of our booking. Luckily the night manager let us use a room for a couple of hours. When the morning manager arrived we were told they have phoned around and found we have been booked at a completely different hotel in a different part of Kos. We called travel up to express our dissatisfaction as its not what we booked. They advised us we did book and go to the correct hotel in the begining and they would need to investigate. Nearly 10 hours later, more calls to travel up and the issue is still not resolved. Were still at a hotel we didn't book and dont like. Very upset and angry that our holiday has turned into a nightmare !
