Hmmm...worst visit had to be Great Adventure last year. I didn't know discounts advertised on TV were online only, so even though I had a season pass, I still ended up paying full price for my nephew. We rode one ride (thank god for flashpass for green lantern), and then the power went out. Couldn't get food, drinks, anything, and it was hot as hell outside. The power came back on fully about three hours later, and while it got less crowded because of the power outage, it was still packed. We did everything we could do in terms of rides, and then we went back on Green Lantern. I hyperextended my knee and had to be carted off on an emergency vehicle to the shady little med station, and then I had to leave the park. Then it poured down raining the whole way home to the point where I couldn't see, got lost, and ended up driving around on back roads with my nephew, who had eaten too much and was feeling sick. Fantastic.
