As a pretty nearly newbie UK traveller, I am pretty intimidated with the prospect that my first thing after I set foot in the country in Bristol will be to figure out how to get to downtown Cardiff. I actually tried to look for it on the web, and it might be just me but I found the whole thing confusing, I didn't know which of the websites was the one to use and some of them would go down at the blink of an eye. I need the cheapest and or easiest way to get to my hotel in Cardiff. which is the Marriott, located pretty near the bust station. As specific as you could be would help me immensely, because I seriously am confused by the national travel system, it seems to be a whole bunch of different companies loosely integrated as far as I can tell.
Also, I am going to try again to get an opinion on whether it is too hot to rent a car w/o AC for driving in Wales. Is it mild enough there b/c of the coast and the mountains or should I pay the considerable extra money? Thanks so much for all those willing to share their knowledge!
