If I'm seeing a girl for the first time, Anth, my procedure, once I've made booking, is to e-mail her telling her among other things that I'm slightly physically disabled and that I use public transport so would be glad if she'd let me know the nearest bus stop/suburban railway station to her premises so that I can ring her for final instructions from there.
If she says, for example, that it's 'about 10 minutes' walk' from the bus stop/station, I then ask her for the number of a local taxi firm [the girls I see all seem to use them to get them from home to their work premises] to take me to her place because I know it'll take me twice her "walking time", especially in warm weather. The extra £3 or £4 is worth it to avoid arriving hot & bothered. I then know how to reach her place if I make a return visit.
Very occasionally, when I've sent the e-mail above, it's produced an offer from the girl to collect me from the local station, which is a real bonus and is always accepted.
