[strike]Anything with snazzy lights on the train is also great: Helix, Rip Ride Rockit, Swarm.[/strike]
Plus vertical lift hill coasters where you're looking up at the stars <3 (Most Eurofighters etc)
I'm sure the coaster I'll ride in the dark tomorrow (Falcon in Duinrell) will be great then, because it has two of the three things you mentioned .
