Surely Efteling can't actually do anything about it?
A front row queue on a coaster with only three rows is a dangerous move. You do risk there being a huge front row queue and just two other rows to soak up everyone else. With short coaster trains you need strict and efficient batching into all available rows. This is something Towers got spot on with The Smiler.
especially when you look at Krake's attempt at one now...
