Delegates coming to London can find very useful information from the Visit London Website– travelling to and in London, tips, what’s on, things to do, etc. It is also possible to book tickets for theatre shows or attractions through the website as well as tours within London and to nearby cities (ie. Bath, Stonehenge, Oxford).
In addition, delegates can download the Visit London App, which is free to download and free to use (no roaming charges) - it offers the same useful information provided as on the website, but it also enables delegates/visitors to create their own itineraries and book tickets via the app.
