I'm 95% sure that we're going to London for a 5 days in Mid to Late May (around the 20th or so). We're probably staying at Hilton Metropole. I don't know if that's centrally located or not but it's where we're staying. The map shows it's located in Paddington just north of Hyde Park. My wife is going to a conference and I'm tagging along. While she's spending time at the conference, I'm going to head out and see the sights. Given that 5 days isn't a ton of time, what tourist traps should I focus on? Is there a decent site out there to point me in the right direction? Since I won't have a car and we'll be dependent on public transport, I assume a simple subway pass will suffice (much like it does for when I visit and tour NYC) or is it different in London? How much should i expect to pay? If you have any other tips/suggestions, i'm all ears.
