Work your way round the "Big 4" first (pick a favorite and do that as many times as possible), do any of the rides around the top (you can leave Rush/Vortex until the end of the day). That's about it really, but depending on the weather either leave Loggers Leap/Tidal Wave/Rumba Rapids for the middle of the day (if the weathers average) or do them straight away (on hot days they're packed by 2/3pm)
