Someone I know had to get the first bus of the day to check in from a
perimeter hotel to the central terminals. How would the check in staff
get there.

there are 5 night routes that run from the Northern Perimeter Road
(which IME is where all the hotels are) to the central Terminals and
one to T5

The [hotels along] northern perimeter road are not a point source, nor
are they mopped up by every bus. It's very patchy.
