Regardless of what park we're visiting, we always seem to mix things up depending on what we're in the mood for.
At Great Adventure we usually end up at Nitro first, but not always. The only time we make a concerted effort to get over there is if it's a cold / windy day during HITP since we sort of feel like we're morally obligated to help them weigh down the trains until they warm up and at the same time we want to make sure we get a ride in if it looks like there's a reasonable chance of a valley
If we get there right at opening we're more likely to head to Joker to beat the crowds, but just this year alone (in about 10 visits or so), I can think of days where we've started at Batman, Superman (it was opening for the day a few hours late and we saw an opportunity to beat the crowds and walked right on to row 1), Kingda Ka, El Toro, Safari and Skull Mountain (long story
) so we really never have much of a strategy.
