I work in an industry where summer is our busy time and it makes it difficult to take time off during the warmer months. This year work are sending me to Swansea for a few days in July, and because I'll get time off in lieu for travelling at the weekend I can follow my work trip with a few days' holiday. It's tempting to be able to take some holiday in the UK in the summer so I'd quite like to, but is there anywhere in the Swansea area that would be good for a short break? I would be on my own which doesn't faze me at all as I like solo holidays. I like cities, I like swimming in the sea, and I like not-too-challenging walks in the country but I don't drive. Would Swansea be a good place? Or Cardiff? Or anywhere else nearby I should consider?
