Just got back from a 14 night in Europe. We had to test twice to get on the cruise but they just lifted the testing requirement to get off the ship and to fly back to the US. I started getting sick the last couple days of our trip but really just cold symptoms. Once home, I tested positive for COVID but my husband was fine. ( both fully vaccinated and boosted.) If restrictions were still in place, we would have been forced to quarantine for 5 days before coming home. We bought a hefty travel insurance policy for this trip so it would have covered quarantine expenses, FYI.
I can tell you that your fellow passengers are most discourteous. I was shocked (after going through this pandemic) how many people freely cough and hack without covering their mouths. I had a bad feeling after our first excursion, I mean half the bus was coughing away. And we ran into several people that said, "Oh, we just got out of quarantine." And they weren't wearing a mask. So, if you aren't afraid of getting sick, travel freely. You are running the risk while traveling though. I wasn't afraid so I traveled but you will be heavily exposed - on the plane, the cruise, buses, etc.
Several passengers tested positive at the port and could either quarantine on the ship or at a hotel. Some people got sick mid-way through the cruise and could either quarantine on the ship or disembark at the next port. Princess had a quarantine floor for guests and it was common to run into guests that had/has COVID.
I believe this is the world we are living in now. COVID is a thing we just have to deal with. If your vaccinated and otherwise healthy, it's like a cold for a week. If you have existing health conditions, immune-compromised, etc. than I wouldn't recommend travel right now.
