Hi Sarlin, my DH and I cruised Alaska on the Bliss 4/30 - 5/7 with two other couples and knew three other couples that were also on our ship (crazy - 12 ppl from the same small town in FL on the same Alaskan cruise). Anyway - none of us developed COVID (or Norovirus) during or after our cruise or cross-country flights (thank you, Jesus!). We took advantage of the 'washy-washy' stations around the boat and used the hand sanitizer every time we passed one. We made conscious efforts to not use the hand rails on the stairs and used knuckles to press elevator buttons. I brought a little hand sanitizer in my purse for use when we'd be in port. We weren't masked unless required - which was pretty much just on the bus tour of Victoria.
The idea of COVID is soooo scary. (At one point, my county had more new COVID cases than anywhere else in the US. We know many people who have lost their battles with COVID. Our eldest daughter had a terrifying battle with it during Delta - her hair is just growing back (yes, weird symptom was loss of hair)).
May you have peace with whatever decision you make in terms of cruising. ❤️
