Good Morning Taffy - yes there are a lot of companies offering trips, but I suggest that first you contact the MSCC travel experts. Quentin English. travel@mscc.co.uk Quentin is arranging accommodation + ferries for the Morgan community.
Hotel or Camping. The first year I went (2006) we stayed in a hotel, last time (2008) it was camping. Completely difference experiences. Good atmosphere in the hotel with a whole range of people. Camping is beside the track, and you are in with the action 24/7.
Track drive. I have also done this twice before (it did only cost £80), and we got three laps of fast driving (well it is in the 4/4). If you are a Le Mans fan - like me - it is a must. BTW Quentin Longish is not charging £150.
