You can get good information at the Travel Information Centre near the Eurostar arrivals area at St. Pancras International train station and at Victoria and Liverpool Street stations. These are helpful if you're looking for brochures for London sights, or if something's gone horribly wrong with your hotel reservation—if, for example, you don't have one—as they have a useful reservations service. The Victoria station center, opposite Platform 8, is open Monday–Saturday 7:30 am–8 pm, Sunday 8:30 am–7 pm; the St. Pancras center daily 8 am–6 pm; Liverpool Street weekdays 7:30 am–7 pm, weekends 8 am–6 pm, Euston station (opposite Platform 10) daily 8 am–7 pm, Paddington station (opposite Platform 1) daily 8 am–6 pm. The one at Piccadilly Circus Tube station is open daily 9:30 am–4 pm. The Travel Information Centre at Heathrow is open daily 7:30 am–8:30 pm, and at Gatwick Airport (North Terminal) daily 8 am–4 pm. There are also London Tourist Information Centres in Greenwich and some other Outer London locations.
