SeaWorld San Diego has confirmed that the new Electric Eel coaster will open for guests on May 12th.In a bit of bad news for SeaWorld San Diego, the local news reports that the park's attendance in 2017 dropped 14%, bringing in about 500,000 fewer guests than the previous year. This is much worse than the reported 5.5% drop experienced by the chain as a whole last year. Hopefully the just announced opening date for Electric Eel can bring about a bit of positive change for 2018.
