Bill, If I were on such a tight schedule, I would as you say rent a car, but one-way, from Gatwick - drive that night late to a hotel in Milton Keynes about five miles north of Bletchley. About 90 miles Gatwick to Milton Keyes - two hours or so late at night. Avis has a return site at Milton Keynes. Leave the car there at Avis. Thursday morning, I would take a taxi to Bletchley Park - the place opens 0930. Spend 1.5 hours or some such max at Bletchley - Train back to Gatwick. I know that you can easily get to London Euston from Bletchley - trains run about every twenty minutes I recall, but I do not know how to get to Gatwick from Euston - figure that out. It would all be very tight, but Bletchley Park is an amazing place to see and only 1.5 hours there would be better than nothing. Here is a snap I took of the "Mansion" when there 15 years ago: http://frobenius.com/bletchley/bl012.jpg If I could see only a couple of things: Hut 8 where Turing used to do his thing and, of course, the Colossus rebuild. It is easy to spend two days there, which I did 2004.
