I agree. They did ultimately close River Country as they opened new waterparks for multiple claimed reasons but it was obsolete. I raised my now adult kids through our annual vacations at WDW and have great memories of both these parks. They are not only stepping into days gone bye but almost impossible to keep up with the known failure of pools and waterparks at age 25-30 years no matter who built them or where they are located. I feel for the upper tier management of these parks trying to make these 'operational' and failing. Just look at the length of seasonal closed for maintenance. It is a loosing battle.
When my kids were small and the water parks operated correctly one park closed in November and came back online in December. The other waterpark closed in January and both were up again in February. Now Disney guest more often than not are opting out and going to Volcano or Aquatica. They are already splitting stays with WDW and Universal so who wouldn't pick Volcano over the 30 year old Disney Waterparks? I feel for those charged with these waterparks, neglected for too long in the same era the other Disney Parks were neglected stateside. Catch-up is hard.
