I have just returned from an All Inclusive 5* family Holiday to Mallorca visiting a TUI Blue hotel and I’m appalled by TUI’s customer service that will unfortunately prevent me from using them again in the future. Upon our arrival at the hotel, I asked the hotel if there was any room upgrades available and what price that would cost. Unfortunately, the hotel receptionist advised me the hotel was fully booked and there are no upgrades available at this time. This was perfectly acceptable and we proceeded with the check-in. Upon booking the holiday we selected a room for 4 guests, my wife, our two daughters (aged 23 months and 4 years old) and myself. Unfortunately we were provided with a room for a maximum of 3 guests. 2 single beds pushed together for my wife and I and a travel cot squeezed in the room for our 23 month old. NO BED or anywhere to sleep for our 4 year old, it very quickly became apparent that the room was for a maximum of 3 guests when we only found 3 bath towels, 3 beach towels etc. We promptly reported back to reception, where we spoke with a helpful gentleman that agreed that a a mistake had been made and that the room was only for a maximum of 3 guests. He passed us onto a colleague to try and rectify the situation. We spent about 20 minutes with the TUI staff member passing on our details and she agreed the room was incorrect and would come back to us within an hour to try and find a resolution. Upon the phone call back from the TUI rep working at the hotel, I was advised there was nothing they could do, only bring a fold up bed up to our room for our 4 year old. We responded that this would not be an option as the room would not fit another bed alongside the travel cot. The TUI staff member agreed and said there was nothing further they could do. Without wanting to waste any further time of our holiday, we decided to separate the two single beds giving one to our eldest daughter, therefore my wife and I sharing a single bed in a cramped room for our 8 night stay at a 5* TUI Blue hotel. We also had to get the cleaners to leave us an extra towel each day as they only expected to have to supply for 3 persons in our room. This massively impacted on our one and only holiday per year, due to feeling tired because two adults squashed into a single bed. Not to mention sharing a small room with 2 young children, which is totally unacceptable. I have tried to give TUI the benefit of the doubt and contacted them twice since returning home to see if they can offer any compensation for charging us for a child place for 8 nights but not accounting for her on the holiday. Unfortunately they have come back to me and asked me to prove the room is too small and that the pictures I took and sent to them of the single beds are not sufficient evidence for them to go on. A great argument for their case, as now I am home from the holiday it is totally impossible for me to take any further pictures or videos that will back up my case. Totally unacceptable for a 5* Star, quite frankly we were relived to get home for a good nights sleep by the end of the holiday! Reviewing companies is not something I like to do, as I always like to try and rectify issues directly, which I have tried to do in this scenario but unfortunately their lack of customer service and compassion has left me with no option. Our family are already looking into booking our holiday for next year, but we have totally ruled out booking anything through TUI due to this. I’m totally gutted with the outcome and quite frankly feel ripped off by paying for something that was not provided, and the only response from TUI is that they understand my frustration but cannot help further.
