Thank you for your response.
I’ve ordered these tests via Princess. Due to arrive tomorrow.
Our cruise departs next Sunday, so plenty time to book appointment.
Not decided whether to book video slot for Friday or Saturday.
Would say I’m ok with technology.
Reading email from test supplier it seems to be straightforward.
As you say, if all else fails we can do it on arrival.
Unsure about how you would book this, but I imagine it will be extremely busy.
This was the reason I decided on the home supervised tests.
Find it all a bit stressful.
Oh for the days, when you arrived with your printed out boarding pass and passport.
