I would mention it, saying you are going to really enjoy the break and time out, and will be recording it for posterity.
Posting on instagram will be great for you anyway, lots of positive feedback. It doesn't matter if she doesn't see it now or as you go. But she will see it.
Go have a great time and keep in touch with those who matter to you. This is a special time for you, a pattern interrupt.
