Myself, I would just wait until you get back. How long is the honeymoon, a week? If so then no worries! Just open it before you leave just to give them some air. A normal fitting lid is not airtight so it will let in some air. I just had the same situation, I left on July 21st and the eggs were due July 23rd. I got home July 28th and they were fine. Good luck!
