The train journey was direct and we stayed at the City Centre Premier Inn. I will say now that the staff were the friendliest and kindest we've ever come across, and I've stayed in a lot of Premier Inns! We were made to feel very welcome. We had pizza at the Thyme restaurant (part of the Premier Inn) on the first night. The food and service was very good.
We also were able to leave our bags after check out, so that we could wander round freely before we got our train home. Nothing was too much trouble for the staff who dealt with us.
Walking into town,we were greeted by a massive seagull!
We had a brief look at Cardiff Castle and I was able to take some pictures.
