That may not be possible with those creaky knees, but at least your wallet won't squeak thanks to the Virginia theme park's July special: every Sunday adults get in for the price of a child's ticket. That means you pay $31.99 instead of $44.99. Regular admission is $54.99, but it gets you two days. This deal is for a single-day admission only. There's a catch (always is) - you can only buy the tickets online. This deal is not available at the gates.
