Returning from sunday evening arrival dinner

Hi

So IF safety is a concern ... what plans should we make returning from
dinner sunday night?

A group of 100 YAPC goers traveling as a group on the 'L' should be okay
(but that is just a guess)
but what about people who want to return later or earlier than the rest
of the group.

Should we be arranging to travel in groups of 4-5 or more and keeping
an eye that no one gets left behind?


Does anyone know enough to say?
