Monday in Orlando, Fla., the golf champ attended a Nickelback concert – where, according to TMZ, he partied backstage surrounded by a security team.

Meanwhile, Elin and the couple’s two children, Sam and Charlie, took off for Sweden, despite the volcanic ash spewing into the skies from Iceland which grounded the majority of Scandinavian and European flights. “Elin and her children have arrived in a very north area, much north of Stockholm,” a source in the Swedish capital tells PEOPLE.
One possible destination for Nordegren: the estate in the Stockholm archipelago she bought last year for about $2.2 million.
“Elin has a large plot of land on the island with four houses – all complete with kitchens,” a source in Sweden tells PEOPLE. “There is one guesthouse and another house down by the sea that has a sauna. She also has a sandy beach all her own and a dock for boats.”
Further describing the estate, called Faglaro Gard, the source says, “Elin has lots of fruit trees in her garden and an oasis of total privacy” – while a source in the U.S. says Faglaro Gard is for the use of Elin’s entire family, whenever they want.
Woods is due to play a tournament at Quail Hollow near Charlotte, N.C., next week, and then in the U.S. Open, which begins June 17.
