• Do you know of any websites that I can check out for cheap bus or train fares to get to Notthingham from London?

• Answer:

  for trains I use http://www.thetrainline.com/default.asp?href=&T2ID=99_200862718584 for coaches I use http://www.nationalexpress.com/ for trains you will come into either St Pancras or Kings Cross stations ... they are right next to each other and share the underground station Kings Cross St Pancras ... the best way to get to Heathrow would be to take the Piccadilly line underground ... see the tube map at http://www.tfl.gov.uk/assets/downloads/standard-tube-map.pdf for National Express coaches you will come into Victoria Coach Station which is a 10 minute walk down the road from Victoria underground and rail station ... from Victoria underground station take either the Circle or District line to South Kensington station, then change onto the Piccadilly line underground to Heathrow
