MILWAUKEE -- More than 8,000 people were on-board Royal Caribbean's Oasis of the Seas, including Casey Hasenstein of Milwaukee.
She was one of nearly 500 people who fell ill from a suspected norovirus outbreak.
The cruise was supposed to be a 7-day adventure to Haiti, Jamaica and Cozumel.
Fresh off a new years engagement, Hasenstein was ready to sail into 2019 with her fiance's family.
"Just go lay in the sun get a good tan go stop we had some excursions we were gonna do," said Hasenstein.
They were able to explore Haiti last week, but then some of her fellow passengers' health began to sink.
"Every morning the captain would come on the intercom and he would announce that there was a huge outbreak of a GI issue that was going on," said Hasenstein.
People sickened ended up with nausea, vomiting and diarrhea. This includes Casey.
Passenger video shows crew members scrambling to sanitize the ship. Some wore masks.
"Every time we walked in a door we got hand sanitizer," said Hasenstein.
The cruise was cut short after Jamaican officials wouldn't let their ship dock.
Royal Caribbean is refunding all the passengers on-board writing in part, "We hoped to give you an amazing vacation and we are sorry we fell short."
With the partial federal government shutdown, it's unclear if the Centers for Disease Control will get samples from the ship to test to confirm the outbreak was norovirus.
