I am so disappointed with Park Dean and with how we have been treated by the manager Mark in Mersea. I am a foster carer, and this was my child very first holiday in his little life and I booked 4 days in Mersea with my other 2 children and 2 small dogs.. Inside the caravan was absolutely disgusting. My house is 10 times cleaner than where we went to. It was covered in false black widows spiders, where i cleaned it for over 2 hours as my F.child who has high needs and suffers from allergies and asthma, and I really did not want to complain!. We were on holiday!! In the morning to our horror, we found a flea or bed bug in my child's bed. I took pictures of everything and showed it to the staff on the dest tgat were amazing in initially trying to get it sorted. The sink was coming off the wall. There were disgusting stains in the bathroom. The sofa had dirty stains all over it, and that with the cushions smelt terrible. My foster child woke up at 3am and was coughing, I opened a window, as an f.b.spider fell in. He was traumatized, so I put him on the sofa with the quilt they gave me, but he kept coughing, and the dogs were scratching. It was a difficult night, to say the least. In the morning, that was when i saw how dirty the sofa was, and I let him lay on a stained quilt. We were there for a total of 20 hours, where the manager was implying the bugs came from me and was extremely aggressive in making his feelings known. We waited for 4 hours in the morning to show staff and supervisor the caravan plus the pictures. It was so hot in there as we were fearful of openening a window as the spiders that were massive kept coming in. My foster child was been so upset and everyone wanted to go home plus I now needed to wash and clean everything from the car before I brought it into my own home, plus go to the vets to make sure they were retreated. We found out from the permanent residents who were all so lovely that the previous people who stayed had left the caravan in a state and had 3 large dogs and they had spent less than 40 minutes cleaning it. I spent over £300 for this gated caravan, and they want me to pay for the 20 hours I was there, and they have said they would only partly refund me. Forget the wifi and the amount of work it was to get permission to take him, washing clean/dirty cloths, car, petrol, de flea the dogs, cloths, food etc I have written so many emails from that night when I got home and still have not had a response. I can not speak to a real person after spending hours trying. This was something my children and foster child had never experienced together, and it was a total letdown. They had no understanding or empathy on the impact this had left him and all of us, especially with how the manager spoke to us and was obnoxious and extremely patronizing. Saying if I went, it was my choice but wouldn't get a refund. I had a responsibility to my foster child to take him out of that situation and moving to another caravan(even though he said he didntvhave a dog friendly one and I would be passing on the bugs I had brought to the next caravan was insulting. So I feel I have no choice but to write this review.
