We are a couple whom were travelling with our daughter. We got married in Orlando 25 years ago and as our daughter just turned 21, we decided to celebrate both occasions with this big trip from the U.K. We paid nearly 4k for the privilege, and travelled with TUI.||The reception was in darkness when we arrived late afternoon, the bell desk and Starbucks was closed, the lights were off and a solitary staff member was present in reception, she did not greet us, but wordlessly checked us in and sent us off to our room which was furthest away from reception and the penultimate one of the top floor of a block adjacent to the 10 lanes of Interstate 4. The room was noisy, smelt of 'weed’ and disinfectant, there were old clothes left on the landing - so we returned to request a new room. She offered us one in an alternative block but we were not permitted to view it before deciding to occupy. We were also asked to prove that the room allocated only 20 mins earlier had not been used or disturbed. We went back to the original room, collected our luggage and provided a video to the receptionist to evidence it was unused before receiving the new room key. We left reception and were immediately drenched by a thunder storm.||We went to the new room but found this to be no better. The floors were sticky, the furniture had sticky labels and food debris on them but it smelt better. The rain was very heavy at this point and we were so tired we agreed to leave it and talk to a manager/housekeeping the next day.||It was then we realised that the bathroom was so small my husband was unable to sit on the toilet with the door closed. We then saw the mould and blood stains on the walls, the hair and dust in the bath, on the skirting, around the door frame which was also swollen and damaged and would not close properly. The extractor was also full of dust. The clean towels were placed over a rail that has mould growing on it. My husband wanted to return to reception and complain. He proceeded to the lifts and saw that the safety inspection certificates had expired over a month prior. ||We then made contact with TUI through the messenger service in the app and were told to see the rep.||We proceeded to reception to meet the rep as arranged the following morning, she did speak with the hotel manager and another room was offered. We asked if we could see it first and were taken to view, however the floors were just as sticky, hair was seen in the sink and on the bathroom floor, and this block had no working elevator. We declined and took the decision to move hotels at our own expense out of concern for our daughters health. She is registered disabled and has a respiratory auto immune condition. After the first nights 'rest' the filters in her respiratory machine were discoloured and full of dust. We told our rep that we would leave some of our luggage in situ but book elsewhere. It was our expectation that the raised cleaning issues would have least been rectified during our absence, but although the beds were made, none of the hygiene issues raised were resolved during our ‘stay’. However we did note on one return to collect luggage that the safety inspection certificates had been updated.||The Avanti International Hotels hygiene is not to expected basic standards. We were advised by a staff member that there are known issues with some rooms being sub standard but it was agreed locally that TUI guests would be prioritised for the refurbished blocks. Disappointingly though this refurbishment is literally some new furniture which still has the labels on! The sealant applied to the external flooring is known to have a fault and is causing the 'sticky black debris' to track into each room. The artex that is on all of the walls and ceilings has trapped years of dust and mould and both the air conditioner unit and extractor fan in the bathroom are relics of the 1970's, constantly whirring and rattling as years of debris and dust have built up. It is certainly not a vacation resort or holiday hotel, but more of a no-tell, motel rented by the hour, this was supported by our experience on the last night where a group were smoking weed on the hall/walkway outside our room.
