I prefer multi-bulb bracketing....might not have been consequent in
my terms either.

Night shots are always a big gamble, so the usual 3 brackets won't do
(in particular not with all the set-up work involved....better safe
than sorry)
If you then start with 1 minute as the smallest increment (=shortest
shuttertime), you end up with 1+2+4+8+15+30+60+120 minutes, or 4
hours total.
Now, you can do all that by hand, and miss a lot of sleep, or you can
let a timer do the job (in particular with those higher-end EOS
bodies that don't consume any power while the shutter is open)).
Lazyness is the mother of the best inventions....;))
