Unless the passholder discount changes next year, no discounts that I know of. This year, passholder discounts are only certain times of the year, and not in summer.
Yes, not for summer, I looked into the pass holder discounts.
However, though it is expensive, you are getting an all inclusive day, including beer and alcoholic slushees, with a dolphin experience. Unless you are outside the US, I doubt you'd find a much cheaper dolphin experience than you get at DC. Plus, for an extra $20 per person, you also get BGT for 14 days. And, if you are going to visit the included parks more than 1 time, which is really nice to do, add a parking pass to your DC reservation (you must call to add it) and for around $25 dollars plus tax, you also get an unlimited free parking pass to use at SW, Aquadica, and BGT for 14 days. Not a bad deal.
Dolphin swims are very expensive, anywhere! We love waterparks, and would definitely go to Aquatica several times.
Any amusement park is expensive. I found nothing is cheap, particularly now that both my kids are considered adults for tickets and food, even though younger one cannot eat like an adult nor ride everything.
Ditto on the adult "kids". My daughters definitely do no eat "adult" priced servings....
The most cost effective use of the DC tickets is to enjoy the other Busch parks more than 1 day each. SW can easily be 2 days, and BGT can be too.
We did Busch Gardens a couple years ago, other than the drive there, great park!
My DD really enjoyed meeting the dolphin, though we all enjoyed. It was a very relaxing day for us, and for that, worth the money to me.
It sounds like an awesome experience! I love the planning part, and searching for deals is fun for me. My DD has been begging for a dolphin swim for years....
