The number of hotels serving Canary Wharf has doubled in the past year with hotels available to suit all budgets.

Budget hotels
Located in London's East End both the Travelodge (www.travelodge.co.uk) and Holiday Inn Express (www.holidayinn.co.uk) serve Canary Wharf via a complimentary 15 minute minibus route (usually morning and evenings only). Prices start from around GBP65 and therefore the hotels make a perfect stop for the budget concious business traveller.
Advantages - cheap and cheerful. Typically relatively new and situated around the Excel exhibition centre so good for attendees to this centre and Canary Wharf Disadvantages - Poorly connected to the City (taxi, bus or DLR are your only options) and not much to do in the evening

Mid-class hotels
Located across the river in Rotherhithe, the Hilton Docklands is not so much in the Docklands as overlooking. Access to the hotel is by free shuttle bus from the nearby Canada Water station (5 min bus ride). Access to Canary Wharf can be achieved via aforementioned shuttle service to the tube and then one stop on the Jubilee line to Canary Wharf or via the boat service which operated throughout the day from the hotel and stopping at the west side of Canary Wharf Advantages - Parking can be included in the room rate, prices start from around GBP90 a night. Can be particularly cheap for weekend breaks if you would like to extend your stay.
Disadvantages - Not well connected. Access via shuttle bus to tube or by boat.
