Since the Brexit vote, the British pound has dropped in value, making London a destination worth considering for 2018. Regardless of currency fluctuations, London is still an expensive city, so here are some travel tips to keep costs down:

  • Purchase an Oyster card for public transit: The Oyster card provides discount pricing on Greater London's extensive network of trains, buses, subways, and trams. Cards are available for purchase at transit points and newsstands, where you can also top them up with more credit. Scan the card at entry points for easier (and cheaper) travel. www.tfl.gov.uk/fares-and-payments/oyster
  • "Overground" it: Try to use the bus or tram when possible. The subway (known as the "Underground" or "Tube") is great, but above-ground transport enables you to see more of the city streets and makes it easier to get your bearings. Sitting in the front row of a double-decker bus, with its panoramic view of shops, historic sights, and quaint taverns, is also a cheaper alternative to sightseeing buses.
  • Take a food tour: London may be the most diverse culinary city in the world, which can be overwhelming at first. We love visiting for the Indian food ("going out for a curry" in local parlance).  Eating London Tours offers half-day tours that immerse visitors in the tasty delights of city neighborhoods. While exploring "Brick Lane — Flavors of India & Beyond" we learned that most of the Indian restaurants, for which the neighborhood is so famous, are in fact, Bangladeshi. EatingLondonTours.co.uk
  • Free museums: London boasts a staggering number of free museums. Beyond old standards such as the British Museum and the National Gallery, seek out some lesser-known collections, such as Sir John Soane's Museum, an off-beat collection of artifacts acquired by the prominent neo-classical architect acquired, or the Wallace Collection, with its world-class display of armory and Old Master paintings.
  • Skip the tea, have a roast: Sunday roast is a British tradition, with most pubs and restaurants offering specials that are an excellent value. While afternoon tea typically costs £40 (about $54) or more, most Sunday roasts with all the trimmings are available for less than £25 (about $33). They're a lot more filling, and far less touristy.

Last of all, don't worry about the weather: If you don't like it, it'll change in 20 minutes. London enjoys relatively mild winters and snow is rare.
