Hi I'll be arriving London on Aug 3rd, just for one night though. I work for DL and a friend is using a buddypass LGWTPA. He's flying in from ARN and i'm picking him up. It's a crazy arrangement I know, but he's never nonrev'd before and I thought i'd be a pal and escort him over. At any rate, I figure since i'll be in London for a night I'll need to find a cheap place to stay...any suggestions?? I've never been to London so i've no idea where to start.
