1 train op should never happen. 0-5minute queues are better than 15-20minutes. If you had 0 queues people would spend more times in shops so more money and people wont be robbed for fastrack. They will be more likely to return and guest experince will be improved. Alton very rarley do 1 train, I'm sure europa never do 1 train, nor disney or cedar point. If they want to be good then 1 train op with 45 min queues need to stop.
