Leave Holly alone,if you'd also read the thread, lights were off on saturday so it was a perfect assumption that the lights should've been off on sunday, so it most likely was a last minute change.Also, the REAL reason for having the lights on was originally to see if it stopped people feeling ill. it did, so they kept it. Good idea really as you don't want people being sick all the time; end of the day they're thinking of a guest experience point of view. Imagine queueing hours for a ride and then feeling terribly ill afterwards. - not fun.
