We have been to a few Warners and everything has been fine. 2weeks ago we went to Heythrop. All looked good. When we finally got to our room we made a drink, unpacked, then I tried to open a window. Like many other people, air conditioning does not suit me - I ge the usual dry cough, difficulty breathing, etc etc. An open window is vital then I can turn off the air-con at night. The window - despite having catches - did not open. A quick phone call to reception and we were told none of the window open except a few on the ground floor. It's 'Heath & Safety'. They could not offer us another room so we had no choice but to leave and come back home. Very disappointed. Warners believe that as they gave us a full refund we are not entitled to any kind of compensation for the loss of holiday, distress through the process of trying to get something sorted, fuel for a wasted journey there and back. Apparently - and you all need to know this - 'many hotels do not have opening windows'. And ' you should have checked before travelling'. Apparently it is our problem to ensure a basic right to fresh air. We disputed the 'Health and Safety' aspect. Air conditioning is certainly not healthy. A lack of fresh air is not healthy. Restricted opening would solve the safety problem. I also asked what would happen if there was a fire in the corridor. We would have no means to exit the room and would be trapped. I was told that I woul - 100% - be able to break a double glazed window. I was not told what I could break it with from my suitcase!!!! Warners do not believe they need to put this information on their website that you cannot open MANY of the windows in their hotels. Warners feel they have been generous in making a full refund. They have offered a £50 voucher but cannot tell me which hotels have opening windows so I can book somewhere else. They suggest I go back to the ones I have been to before. This unacceptable attitude has put me off ever using Warners again. Apparently a lack of fresh air has never been a problem before so they will not be looking to do anything about it. Be warned.....check EVERYTHING yourself before you book. I was told that the problem with booking online is that you cannot check these things and you should ALWAYS phone to book!!!! It's 2024........?????
