Example: I happen to think Discovery Cove's so-called "Dolphin Encounter" is one of the best examples of how NOT to run a dolphin interactive program (and a grossly overpriced one at that) on the planet.
I have that opinion because I've traveled extensively, visited numerous zoos and oceanariums, and have experienced nearly a dozen dolphin 'swim-with' programs at other parks, both in and out of the US. I've also served as a volunteer trainer's assistant at two parks (Oklahoma City Zoo and Sick Flags Magic Mountain, the latter back when they still had a dolphin show).
That exposure has given me very high expectations of any dolphin interactive program. Only two programs have even come close to meeting those expectations, and both are based in Mexico.
So, in summary: I would never even consider spending that much for a "VIP tour" at any SeaWorld park (heck, you'd have trouble convincing me ANY SeaWorld park is worth a visit, period).
However, someone who's never been exposed to any such thing (and who is unfamiliar with SeaWorld's true nature) might consider it a perfect and worthwhile opportunity.
There's simply no way to tell short of taking the thing, and venturing an opinion based on your own perspectives and experience.
To me, it's not worth the risk (of dollars).
However, with the extra money, you can just buy another night at the hotel and visit the park on two consecutive days. A decent two-day touring plan should afford you the opportunity to see and do everything at a very leisurely pace.
