Considering the Natal B&B in Cambridge?

From London/Stansted to Cambridge by coach by Airpunk
National Express has an excellent coach service linking Cambridge with Stansted Airport (and also Heathrow and Gatwick). Service 797 runs twice an hour during daytime with a more limited schedule in the morning and late in the evening. A return ticket from Stansted costs 12 pounds (2007). This offer may be interesting for all the Ryanair and Easyjet people who do daytrips from their hometown to London. If you know London well enough, use your low-fare flight for a trip to Cambridge instad.
