I'm going to London for a weekend I'm going on the Friday night and I'll be there Saturday, Sunday and i will travel back Sunday night. I'm going to visit the 02 arena and some other sights that i would like to see i have been there many times before but I haven't really done any of the attractions but i have seen most of the sights there what else is there to do I have been to Hyde park... how much money would I need and where should i visit etc...? right now i am planning on £120 to £150 but i am not too sure obviously i am staying with some one so there is no extra cost for accommodation or anything like that.... thanks for any good advice!
