John Travolta, mourning the death of his son Jett earlier this year, took a solo trip to Tahiti over the weekend.

Travolta, 55, flew in from Australia on Saturday morning on his private 707 and stayed at the upscale Intercontinental Tahiti resort in a room with panoramic views. He was not spotted outside the room until he left the island Sunday evening, sources tell PEOPLE exclusively.

“He told the hotel manager, ‘I don’t want to see anyone. I only want to rest,’ ” a source tells PEOPLE.

The hotel’s management would not confirm Travolta’s visit.

Before flying off, he posed briefly for a picture with three tourist bureau greeters.

Since Jett, 16, died from a seizure disorder in January, Travolta and wife Kelly Preston have kept a low profile and tried to stay strong for their daughter, Ella Bleu, 9.

Travolta took his Polynesian respite four days after what would have been Jett’s 17th birthday. Earlier in the week, Travolta and Preston vacationed in Melbourne for three days.

Tahiti is a familiar stomping ground for the Travoltas. The family included Tahiti in a long vacation in 2003, Preston told PEOPLE at the time.

A source who knows Travolta says of the actor, “He is still in mourning about his son. This is not easy and everyone has their own process. He’s always there for his family but he is still healing.”
