Funtown Splashtown USA in Saco is turning a potentially harmful PR nightmare into a coup. On Monday, the waterpark plans to bring 11-year-old Dylan Dean, the child who was allegedly bullied at a similar named waterpark in Texas, to Maine for a vacation with his family. Funtown Splashtown USA late last month became the victim of mistaken identity after receiving a torrent of angry phone calls, emails, tweets and Facebook posts after a television station in Texas reported that Dean, who they reported is autistic and has a medical condition that causes him to gain weight, was allegedly bullied for being overweight at Splashtown in San Antonio, a waterpark that has no relation to the park in Saco. Ed Hodgdon, who is in charge of marketing for the Saco park, said the negative reaction on Facebook was swift and overwhelming.
