Departing on Saturday, so can test "anytime" on Thursday. Planning to use emed BinaxNOW purchased through the X link.
But Thursday must have some time-zone dependent beginning time.
What's the earliest that anyone has tested on the 2nd day before and has any time been too early? Does 12:01 AM Eastern time count? Pacific time?
Well, I can say absolutely that the test we used for our November 2021 sailing on Reflection were dated on Thursday 11-2-21 for a 11-4-21 sailing. Not being a Celebrity Executive with decision making authority I can not say ‘absolutely’ what will or will not be accepted at the time of your sailing.
The Celebrity web site says two days, hours and time zones are not mentioned.
