Just saw it too--no big shock, I guess. From the Sentinel, effective tomorrow:
One-day, one-park ticket prices effective Saturday are going up at the gate to $63 for adults and $52 for children, up from $59.75 and $48. Tax is extra.
But if you buy your tickets online, beginning Tuesday, you can still get in for 2005 prices, $59.75 and $48.
