In reply to Steve Wetton:
Obviously travel, particularly for tourism, will get sorted out adequately.
It's far from obvious that this will happen in time, though, so we're avoiding foreign travel for a month or two after the UK leaves the EU, as we don't have any specific need to go abroad during that time and there's lots to do here anyway.
That might be overly cautious, or may prove to be a very good idea; either way it's a good chance to explore some of the things we want to do in the UK.
