I've heard a few reports from people who have received this survey.
The biggest thing that has stood out to the people I've spoken to is that the park is pitching a series of Water Country USA-only pass options.
This, of course, directly contradicts the park's stated position with the new Membership program. The park said over and over again that their season-long admission offerings moving forward would include everything the SEAS Williamsburg properties have to offer—this was their repeated defense of not offering BGW-only pass.
If they decide to launch a WCUSA one-park pass, many BGW pass members who were just forced to buy a WCUSA pass when they didn't want one will be furious.
Additionally, I was dumbfounded to see many screenshots from the survey which included perks on these proposed Water Country USA passes that were vastly superior to those offered to even top tier membership holders. I hope that the park isn't foolish enough to actually consider bringing such passes to market because, frankly, their new membership holders will raise holy hell.
