Where do I start! I feel so utterly let down by the Hilton, their failure to resolve my complaint, the lack of replies, the ruined weekend and now hesitance at giving the Hilton Group any more of my business. The facts - 8th Feb - booked 1 room for 2 nights (22+23 March) costing £236.55 and also another room 8th Feb - (22+23 March) costing £259.35 Due to adverse weather I called on 22nd March and asked to alter the dates on both rooms to 23 + 24 March - The manager was more than happy to help out and assured me it would not be an issue, I got email confirmation and info on the Hilton App, all updated. 23rd March upon arrival I was advised that they had mistakenly only changed 1 room, but this was not an issue and booked another room for me, lots of reassurance it was all sorted, off we went and settled into our rooms. Due to the late hour, we opted for room service, limited menu but to be expected. Next morning we went for breakfast, self-service buffet but could not locate GF on the counter and found hardly any choice for a GF diet which was very disappointing after paying a premium rate. I had to locate the staff, managed to get a small pack of GF cereal, 2 pieces of toast and 2 poached eggs (quite vinegary)...toast and eggs came 5 minutes after each other. Went out for the day - upon our return, I found initially my key would not work (the other room was ok), went back to reception and got it re-coded (no mention of any issues) back up to my room and found it had been cleared and cleaned and all my personal items removed, this included medication, clothes, refreshments, sweets for diabetes and drinks, along with toiletries. Off I went down to reception again. The Receptionist advised me I must have checked out but forgotten my stuff (really???) ...so they had cleared the room and stuffed all my clothes into a bin bag, the receptionist realised after checking the computer that this was the Hiltons mistake and whoever had booked us in on night 1 had screwed up. It took them 35 minutes to work this out, they returned and advised me that all my stuff was now back in the room. Off I went back up the lift, to the room and found all my items literally dumped on the bed, some of my items were missing my diabetes sweets, refreshments and shampoo and conditioner (lush) toiletry items, off I went back down, I complained and the reception gave me a voucher for 2 drinks. Later that afternoon, we went to the Exec lounge (as this was part of the package we had booked) only to be advised we did not have access, how embarrassing, trying to get in! I spoke to the gentleman on the door and explained the issues we were having, he agreed to let us in (no GF options though) , he tried to give me another voucher for deserts which I declined. I explained I was very unhappy (having ,my personal items thrown away or in an old binbag) with what had happened, having my personal items thrown away was very upsetting and for reception to feel that 2 drinks woul
