Sam and Charlie Woods were spotted at the marine mammal park with their aunt, Josefin Lonnborg, who is their mom Elin's twin sister, in town visiting from Europe.
"The family took a tour of Sea World that lasted for a couple hours," a source tells PEOPLE. "They had a wonderful time, everyone was laughing and enjoying the park."
Sam, 2, and Charlie, 11 months, looked happy as they fed the animals then watched the popular "Believe" show starring Shamu the Killer Whale.
A couple of weeks ago, the children and their mother Elin temporarily moved into a friend's home in Windermere, Fla., not far from the Woods family estate.
"The house is beautiful and they seem to enjoy being there for now," a source in Orlando tells PEOPLE.
