Heathrow Airport Hotels
If your business travel will take you to London soon, BootsnAll has a great resource for hotels near Heathrow. With added security (again), it may be worth your while to plan to stay near the airport the night before you depart. This site lists hotels by name and includes site links, phone numbers and email addresses for the properties, along with a map of the property in relation to the airport. You can even find the hotel that best fits your departure Terminal.
Booking through this site gives you great deals, while supporting the Business Travel Logue and the independent content provided by the BootsnAll Travel Network.
Enjoy London and happy travels!
