The Castle itself was amazing. However our short tour was unexpected. We had visited Carrick town for a meal as a family of Grandmother , Daughter and three Grandchildren aged 4 and under. Afterwards we had a walk around the harbour and for the first time saw the gates to the Castle were open. My Daughter and Grandaughter needed the bathroom and in the shop asked if there were toilets, to be told " Yes. But you will have to pay £ 12 as they are inside the Castle. !!! " It was half past 4 and the Castle was due to close shortly, but we were not allowed to use the facilities so my Daughter went ahead and I paid £ 12 . As I paid I mentioned to the member of staff that the last time I visited was in the 60s as a child on a school trip. I seem to remember some kind of Zoo with dark sone stairs and Monkeys in cages . I asked if he knew about this. I was very upset at his response, telling me that I was thinking of somewhere else, getting mixed up and laughing. As I took my ticket and browsed in the shop I overheard him telling other staff about what I had said and having a good laugh at my expense. It left a sour taste in my mouth and although the internal staff were lovely ,and the Castle beautiful , we were guided out without seeing the whole thing due to having to buy our ticket at this late hour , I felt upset the whole evening. I am in my 60s but I am definitly not senile , or deserve to be laughed at by someone who is a face that greets visitors, a supposed welcome , full of knowledge. He should have put customer service first and checked out my comment to see if I rembered correctly and if Monkeys were at one time kept there, added it to interesting facts , not sniggered behind my back. 10 out of 10 for the Castle and other staff . 0 out of 10 for the unpleasant an humiliating experience in the entrance and shop.
