Let me share with you dueling strategies for conquering a park:
1) Wait to go on the best ride at night, about 2-3 hours before closing. This way, the entire day you still have the best in front of you, PLUS you still have time to go on the best ride again, PLUS you get the experience of riding the best ride at night the first time you ride (night ride on best ride not diluted by previous day ride on best ride, i.e.the law of diminishing returns)
2)Go on the best ride early--lines will probably be shorter AND it might theoretically be a better ride than had you ridden it at night because the the night ride experience would be lessened by the fact that you had already ridden other coasters during the day, and the novelty will have worn off.
I pick strategy 1.
