thanks for answering, I went to the two things I really liked both but the truth is that we had little time, visits only lasted about two hours so the time was flying and we had much to do ... we saw the national museum of the Navy, we walk through Oxford Street let us in in groups of two to harrods, got on a ship that sailed the THAMESIS etc. ..
the last day we were unlucky, we were in Greenwich and were going by train to downtown, the return trip, the departure station we canceled all convoy, we had to catch a train to Luton to catch a bus after we would leave the meeting point and ending at the Gatwick airport, several colleagues lost their documentation, I had a friend who also stole his card cuendo enbarque had already gone through security checks. finally an adventure!

See you tomorrow!
bye
