Celebrity Solstice cruise ship passengers Ron and Loretta Rutkowski enjoyed some extra time in Port Chalmers last night.
The couple from Arizona said the cruise ship stayed in Dunedin to avoid choppy waters.
As a consequence, passengers on the 14-day cruise bypassed planned stops at Dusky Sound and Doubtful Sound but would sail to Milford Sound as planned today before heading to Hobart.
The unexpected night in Dunedin was a "positive" experience, Mr Rutkowski said.
"We didn’t view it as a negative. It’s given us the opportunity to see more stuff," he said.
