International test before sailing

[epcot1stfave]

DCL website states a pcr test no more than 3 days before sailing. Does this include day of sailing eg sailing on Sunday test Friday or can I test on Thursday which is 3 full days beforehand.
Or is it 72 hours to sail time eg test Thursday at 5pm for Sunday 4pm sailing which would be within 72 hours.
We need to travel to London on the Friday, flight to Florida on Saturday for Sunday sailing so timing of pcr test is crucial as they usually take upto 24 hours for result, so getting the result while still in the UK would be best.
I know at the moment an antigen test is sufficient for entry into the States but getting the PCR timing for DCL is what has me confused.
Thanks Michael

Are you traveling with unvaccinated children? Fully-vaccinated adults or children do not need the pre-test, just the embarkation test given at the port. If you do have young ones needing to test, I believe it is days and not hours. So testing on Thursday should be sufficient.

We are both fully vaccinated and a booster, no children. So we only need to do the antigen the day before our flight to the states, good to know saves a lot of running around for us.
Thanks for your help

Thanks Michael
