Cardiff
I do not know whether I was told this or simply made it up, but one of the best times to visit Cardiff is when the daffodils are in bloom. As the national flower of Wales, they grow everywhere from parks to castles and figure very prominently on all kinds of tourist knickknacks. I planned mine and Johnny’s trip precisely for this time. Since morning train tickets are cheapest on Saturdays (and that by a wide margin), our choice of date was set. It was also set well in advance, as tickets become more expensive the longer one waits. Of course, this meant that we were left at the whims of the weather, and as the day of the trip drew near, the forecast did not look particularly auspicious.
