I'm an expert, just got out! I was on the Magic last week. Felt very sleepy Saturday and woke up Sunday with aches and pains and other symptoms. I, being a responsible adult, called to get tested. A nurse came to my room and did the test, they requested I stay in the room until the results but it would be fast, within a1/2 hour.
It was positive.
I was moved to an isolation room, by men who cleared the hallways and sprayed the halls behind me. The isolation room was actually nicer than my inside stateroom, it had a window and a sofa.
Once in isolation they gave me a baggie of Tylenol and Nyquil. Also got a bag of snacks, chips and candy. All my meals were delivered to the room, I was told I could order from the dining room or regular room service, no charge. There's a table outside the door and room service would leave the food there. Every meal came on paper plates and the silverware was wood. You get a hazmat bag with your meal to bag the tray when done.
I also got free internet and a letter giving me some credit for the next cruise, approximately what I paid for the 2 days I was confined.
I didn't have the cheers package but it was my understanding that they would deliver drinks. If you're a smoker they ask you to please smoke in the bathroom. If a child gets sick a parent is confined with the child.
Disembark after 9:30, when everyone else is gone. They bring your luggage to a staging area and all the covid group gets escorted off the ship. You're told to drive yourself home or have someone pick you up. wink, wink.
And that's what happens on the Magic
