My sincere commiserations.
On our very first cruise, a short trip to Hamburg earlier this year, I caught covid and was moved to an isolation cabin. My wife continued to test negative, so she remained in our original cabin, but even though she could roam the ship as long as she tested negative, she was restricted to room service meals.I believe the reason was that she'd have to remove her mask while dining.
Still, the little bit of the cruise that we did experience impressed us so much that we re-booked and we're off to Scandinavia on the Queen Victoria departing Sunday.
I hope you aren't put off and will also cruise again. Good luck!
Incidentally, here's my wife and I in Hamburg, just before I tested positive.
If anyone spots us next week on Queen Victoria do come and say hello, we're both well so there's no risk!
