Who has lost a baby changing mat

I found a cot bed mattress on the beach yesterday. It is a portable mat that you can attach to the back seat of your car. It is a good quality mat, made of some easy-to-wash fabric. And it really looks brand new, as if it has never been used. There are some sky blue, navy blue and black dots of various sizes on it. There is also a travelling bag with the same patterns. I found the items late in the evening, when I was coming back from a walk with a group of friends. I guess the mat belongs to somebody who is staying at our hotel because the beach is visited mainly by the guests from here. I also know that we have a few young couples with children here. So please let me know if you have lost a baby changing mat. I also found some towels on the beach. They were hidden in the sand and I only noticed them because my foot got tangled up with one of them. There are three towels: a blue one with some zigzags, a red one with yellow hearts and a plain purple one. I also found some children"s books and toys in the common room. I have put the baby changing mat, the towels and the books in the storeroom on the ground floor. Soon there will be a little lost and found pile. Please come to see me at the reception desk to get more information or see the found objects.
