We were on a TA on Princess leaving Ft Lauderdale for 23 days. After the first 15 we docked at Southampton and those not going on to sail the British Isles would get off. We were staying on until 2 days before Southampton, when they tested us, only to find we had covid. All we had was a runny nose. They took us off and bused everyone to the Radisson Blu at Heathrow. They paid for 5 nights and told you to turn everything else over too your insurance first, including receipts for food, medical care and cab fare first and then file with them. That's all the help we got. From talking with our fellow cruisers and researching ourselves, we found we did have to stay 10 days frm positive test unless you tested negative. There was a testing place right behind the hotel so we could get tested. You also could get a letter of recovery on line frm a Dr at Quickmd.com for $75.00 to use after the 10 days in case you were still positive. It verified you should be safe for travel but not contagious. You also had to fill out a form called Attestation to get back in the US. We ended up coming home the original day we were supposed to as that was the 10 days because my husband was still positive. After testing 3 times hoping we could come back sooner, it just wasn't in the cards to come back sooner. After all the worry and expense, all they asked for at the airport was the Attestation form. Princess ended up dumping off 3-4 buses of people over the week we were there. Princess was absolutely no help. If not for everyone else talking in the lobby who know what would have happened.
