If you've the time, I've a couple more questions..

...Roughly what kind of spacing would you recommend when replanting?

I normally give them about two feet but then I plant two or three at a time
at each station.

...on the assumption that I end up with a surplus, how long do you
think these will survive before replanting? I'd like to give some to
a friend and as a channel-crossing foot passenger I'd prefer to travel
light, just chuck them into a bag rather than having to carry pots of
soil they've been planted in. I'm thinking in a week or two. Is
there a risk of them drying out?

Personally I would not try to keep them unplanted for so long. Perhaps a
couple of days at most.
Can you not plant them somewhere else for a while?
Anyway, to transport them dig them up, clean them of soil, cut the leaves
down by a half and wrap the plants in damp paper ensuring the roots are
covered, that's how they are sent out by specialist nurseries.
The person the other end needs to plant or pot them up asap. When I have
received plants like that I pot them up until the next spring so I can give
them some TLC for a few months because my experience of planting them
straight out in the garden is not good.
