Ever heard of Disney’s River Country? This was the first Walt Disney World water park, but it wasn't built up to today's high standards. There were constant repairs made over the years, and it was closed totally in 2001 for maintenance. We don't know why they never bothered to reopen, but maybe it was too excessive to keep up, or maybe they just moved on to bigger, better parks.
It's now just another abandoned water park, in the graveyard of bad projects. It's full of plants and most say it looks terrible. In 2018, Disney announced the site will be made into a new attraction.
