answer:First, is your passport still valid? If not, there is a fee involved for renewing it. The next step is to check into flight costs. Depending upon where you are, it might be cheaper to fly into Manchester vs. London. Both will require a long train ride or additional flight to get you closer to the Newcastle area. England still uses the pound and not euros. You’ll want to get some money exchanged before you go. I do this at the airport, as there isn’t a convenient place in my town. I got a debit card there that holds larger amounts and a smaller cash amount for pocket change. If you are staying at a friend’s house, it should be a relatively cheap trip, other than the plane ticket. The trains are not that expensive.
