Yeah... I sorta took my car one morning in June and drove. For hours. Without really intending to come back. I ended up on the other side of the state before I ran out of petrol and realised I had forgotten my wallet, so I had to ring my Dad. Boy, was that an awkward phone call.
We wear white tennis shoes in liverpool! I have 3 pairs :P So thats crap :P
Have a look on http://www.newlook.co.uk/women/store.aspx
theres loads of really nice stuff on there that most people here would wear and im pretty sure you can get similar stuff where you are :) just dress comfortably to be honest!
The only thing i can think of is the Thames cruises which stop right next to big ben for the chimes and the firework displays :) Pretty pricy though at £100 per person.
Either way I'd try to get near Big Ben on new years eve, thats where most of the partying happens :D haha
It all depends on what you like really, theres LOADS to do :)
And its good to be excited, hell i get excited when im going to my own city centre :P I live in Liverpool, its brilliant!
