Given the following context:

Single father Bob Holcomb, a widower, is unhappy with the guitar-playing boy Kenny his daughter JoJo chooses as a husband-to-be. An executive with an oil company, Bob accepts a transfer to the firm's Stockholm branch and he takes JoJo along, hoping it will distract her.
Sweden turns out to be far more liberal sexually than the United States. Bob, having met an attractive interior designer, Karin, decides to take her away for a romantic weekend at a mountain resort.
JoJo, however, has accepted a similar offer from Erik, who is Bob's new assistant. Originally seen as a respectable suitor, Erik turns out to be a playboy and a cad. A girl thought to be his cousin, Marti, is actually a former girlfriend.
Kenny turns up and brings Marti along to the resort, where the three couples continue to awkwardly encounter one another. Kenny finally has his fill of Erik, knocking him out with his guitar. On a voyage home, the ship's captain performs a double wedding ceremony, that turns out to be invalid, due to a navigation error. So it needs to be done again.

answer the following question:

Where do Erik and Jojo go?
