Last year I went to the Nine Worlds Geekfest, and I was back there again last weekend. I enjoyed it, and I've already bought my ticket for 2015, so I'd recommend it to anyone with similar interests.
Last summer, I went off to Germany for a wedding, then I took a detour on my way home so that I could visit Disneyland Paris. I had a good time, although it would have worked better if I'd done a bit more advance planning.
