Just got off yesterday also.
Found the service just fine although training going on.
Bar service no problem for us beer people.
Just a few big things ( 2 elevators , terrace pool) closed the entire 7 night cruise for maintenance that was not happening , along with the waterfall & several water jets in the Spa pool.
Of course the rust which could be expected on a 20 year old ship.
A couple of good shows , food was good in Brittania and even better on Bamboo Night at the Kings Court Alternative and the Verandah.
Been on several of these Independence Day cruises but nothing close to the celebration put on by the QM2 on Deck13 that night .
All in all a good cruise until the final night. Despite folowing the onboard Mask Rules , 4 Vac's , we both came home with Covid19 .(I'm convinced Masks don't help.
