Yes... can do, but I don't think it will be too bad next week. It could even pour with rain and be freezing the whole time. The weather is extremely unpredictable. At the moment they're thinking rainy up north and dry and 'warm' in the south. But they also say that it could be 'changeable' next week =S
Well..I live in England. I live right by Stonehenge:)
The weather is pretty crazy at the moment. For the last week it's been pretty hot...but then today it poured down with rain and is meant to continue raining until the weekend, where it's gonna get hot again. All I can suggest to pack a variety! Umbrella's/jackets are always handy but do pack shorts or something in case it gets crazy hot again.
I'm not so sure about the irish folklore evening as I have no idea what it would involve either, but if you're interested in castle's then you would probably like Windsor castle ...I mean the Queen lives there (sometimes):D and it's the oldest and largest occupied castle in the world apparently.
Oh and also on West end reccomendations... The Lion King and Wicked are amazing:)
Windsor castle isn't brilliant, but I guess from a tourist's [no offence intended by that] point of view it could be :\
I'd definitely go for the Irish Folklore evening - sounds impressive. :) You'll have to see what's on as for the shows by the way but I'm sure I could recommend you something.
England, Ireland, Wales and no Scotland! :O. /melodramatics
