Funny. We used to cruise a couple times a year but are in the same boat (bad pun) now as you. We have natural immunity as well and won't cruise until they drop the mandate. It's a shame too because they (the CEO's) think that they are catering to the vaxxed and that that's the demographic that will fill their ships...they will soon see that this line of thinking will sink ships when the bottom falls out of the economy. In the meantime, I continue to get 2-3 glossy brochures a week trying to entice me back on board.
