Passport Renewal best practice.
1. Get the form in advance at the DFA
2.Photocopy passport page 1- 2 copies, passport last page - 1 copy, valid id's back to back - 2 copies
3. Go to a Saturday at exactly 9 AM they will open and submit your form
4. Wait for your name to be called
Fyi they will prioritize you, if you are renewing your passport with a minor.
If you are really in a hurry, get a travel agent to help you, they are given priority as well.
