The Original Tour, a hop-on hop-off open-top bus tour, is a great way to see the sights of London. The tours are informative, fun and provide a great introduction to England's capital. Ride the full tour, without hopping off, and decide which sights to see. Create your own itinerary and set your own timetable. Hop-off at places of interest; hop-on a different route. Take the bus tour to the Tower of London; take the river tour back to Big Ben. Family Travel Tips: Book online and save. Tickets are valid for 24-hours. The following are included in the ticket price: unlimited travel on three bus routes, a river cruise, three walking tours and children's activity pack. It's near impossible to take advantage of the entire offering without a bit of advance planning. The yellow route has live English-speaking guides; all other routes have multilingual (English, French, Spanish, Italian, Russian, German and Japanese) recordings. The live guides are of varying quality but are, in general, superior to the taped commentary. A children's channel is available on red and blue routes. The live guides gear their talks to a tween's understanding. Each routes is roughly 2.5 hours excluding hop-offs. An open-top bus tour is not an alternative to the tube. They are a horrendously slow means of transport in peak traffic hours and on special holidays, such as the Queen's birthday. Kid's packs are available from the company's Trafalgar Square center.
