The upside is that you will be guaranteed passes, even if you show up later in the day.

Wait until you get into the park and see some of the posted wait times before you decide whether to spend the extra money for the passes.Set your sights on three or four, and be prepared to wait in lines. You could leave in the middle of the day when the crowds are the heaviest, enjoy a nice meal outside the park, and return later in the day when the lines thin out again. Arrive at park opening before most of the crowds and go immediately to the most popular rides.If you don't mind getting wet or hot (heed your inner mom and don't forget to apply sunscreen and keep yourself hydrated), the parks will generally operate rides in inclement weather unless the rain is excessive or there is lightning forecast. Nothing keeps crowds away and lines short more than crummy weather. Go on a day when it is threatening rain or will be very hot.For instance, a park might run only one train on a coaster that has three trains, thereby still making the lines long. The problem with this strategy is that Six Flags might cut back operations on its rides during slower days.

Avoid weekends, go early or late in the season, or otherwise try to zag when everybody else is zigging. Plan to visit on a day when it is less likely to be crowded.
