A postcard about my holiday

Hi! This time I tried to write a postcard about my holiday! What do you think? How did I do?

Dear Jean
How are you doing? I'm writing to you from Kołobrzeg at the Polish Seaside. I'm there with my family. We have a great time, though the weather isn't so good, as we'd like. Therefore we spent our first day on a campside, where we are staying. Yesterday morning we climbed up to the lighthouse and the view were really great. And in the afternoon we went to the beach, where we were sunbathing and we were having a bath in the Sea. Tomorrow we're taking a treepboat on the lake next to our campside and in the evening we are going shoping and then eating ice-cream.
On Saturday we're buying some suvenires and on Sunday we're coming back home.
Anyway, I'll tell you everything, when you will arrive to me next week.
Hope to see you!
Bye for now!
Kate.
