Unless you've previously cruise with
DCL before, yes.
I'll also point out - you don't have to enter correct information for the PAT page to open. Sometimes the default answer, or gibberish, will be a quicker entry. The DCL website doesn't recognize that the information you've entered is correct, only that you've entered
something. Entering that you are arriving by private transportation is quicker than supplying flight numbers/times. Entering that you are paying by cash is quicker than supplying credit card numbers/expiration dates. Entering that you are using birth certificates is quicker than entering passport numbers/info.
You can always go back and "correct" any entries that weren't complete

after you've selected your PAT. Or at anytime prior to 3 days before the cruise.
