The reason I wouldn't wait is because it's a pay now or pay later situation. On the Sunday of checkout, all I care about is 1 trip to the airport.

However, on the Sunday of check-in, besides the NEX, I may want to take the train elsewhere after check-in. That would at least be 3 train rides (NEX, train from hotel to say, Shinjuku, and then the ride back) vs at check-out, a train ride on the NEX back to NRT.

I know personally, for an upcoming trip, I might want the NEX Green car from NRT then since I have to pay, take the Skyliner back to the NRT (which is cheaper than the NEX.

Hence, why wait?

If your flight out is on Sunday, you would need to pay for the ride back out to the airport. You could also activate the Pass immediately on arrival but designate the next day (Monday) as the "start date,' but then you would need to pay for the first train into the city on arrival day. Pretty much the same out-of-pocket expense.
