Serial traveler Matthew Kepnes did a
10-day trip to London for only $700. Here's how he did it: "Using my own travel hacking tips, 10 days in London only cost me $710 USD. That works out to be roughly $70 USD per day. And that's not just my day-to-day expenses. That includes EVERYTHING - my flight to London, my hotel, transportation, food, drinking and attractions."
