If you come here for the game be prepared for massive traffic jams. I don't recommend trying to learn to drive on the left in this kind of traffic. Also keep in mind taxis/uber get pretty expensive with the traffic delays. It cost well over $100 to take a taxi from the airport to Victoria Station as traffic was heavy. The weather then likely won't make the game time the easiest to tour the city. It will be cool, cloudy & often windy. Still the best way to get around is the Tube. Learn their subway system ( it's easy) and you can get around quickly. Transfers can involve long walks. It's old, so it's not disability friendly. You can have a great time here, but do a little research first. If you want to splurge they have great theater and a reduced price ticket shop near Trafalgar Square. You could also try the Scottish Beef. I like a little place called Boyd's. It's a hotel resturaunt but has great beef. Travel light and you can take a train/subway connection from the airport to near your hotel. If you're all in on the game book a hotel early that's near the stadium. Food prices are higher than the states. Flying in Saturday (always overnight departing on Friday) would be exhausting even if you can sleep on the plane. Loaf the day you arrive if you can afford it. Try for a hotel/breakfast package. Lots of Starbucks here and a McDonalds on many corners & at many train stations. People are great and very helpful. Accents can be a little tricky. One last tip; be careful crossing the street. US citizens typically look left when crossing. Here you have to look right as that's your inside lane. In tourist areas, they print it on the street at crosswalks.
