There will be a more detailed list later, but for now, make sure you have a passport that is valid for the length of the trip (March 2026). Some other things you’ll want to buy if you don’t have them are good walking/standing shoes (waterproof is best), an umbrella & rain jacket, and a UK power adapter.

This trip costs $1000 plus airfare ($700-800), which covers all lodging and meals while you are there, except for one day off for tourism.
