The only two times I've been to India I had in effect a United Nations
"diplomatic visa", so wouldn't know.

But what if I were to organise a meeting, booking a conference room,
greeting guests and holding a seminar (where I was speaking). Is that
closer to "work" than "business"?

In India, that would likely require a conference visa which is
different to a work or a tourist visa. I have one in my passport.

But I have no opinion as to whether the Gatwick overbridge would
have made it easier to get to the conference.
