Busch Gardens announced that it's raising daily ticket prices by $2.00, to $72.00 for adults and $62.00 for children (ages 3-9). The Newport News Visitor Center is still discounting the tickets by $15.00; I'm not sure about discount coupons out there.
They're also introducing a *Fall* Fun Card Pass, good for unlimited admission from 7 September through 27 October. The cost is $72.00 (a great deal if you're going to visit multiple times) for both children and adults. The price at the NNVC is $67.00.
Since neither the ticket nor the pass includes parking, I suggest making friends with a local so they can drop you off. :-)
