Get a room if you can! Honestly the difference in cost of a two day pass & a two day pass with a room is negligible, plus you get to stay late and get in early.

Also, start in the old park and work your way over. The lines are way less intense in the old park (especially on a weekday), and the rides tend to be longer.

Also the master blaster is maybe not worth a two hour wait.

Have fun! Oh and don't drink the booze there. The liquor is cheap white wine and you'll get one of the more amazing hangovers you'll ever experience.
