Don't listen to these guys!
Bring all your gear and hit the beach! If you don't break her in now she'll get too spoiled. Get her some waders and get her out there. On one of my anniversary's I towed my skiff and brought all my gear to Chatham. I took her out on the skiff and we packed a nice lunch and stayed on the water for hours. I even shore fished while she read a book in the car for an hour. Get her used to it now cuz if you don't she'll just expect you to spend your "could be fishing time" with her doing stuff like shopping and lord knows whatever else. If she gives you a hard time that could be just the tip of the iceberg on other stuff. If you cave now, trust me you'll be asked to cave again and again. Be strong go fishing!
You'll have time to that other stuff during other parts of the day and make sure your sincere and caring when you do them and then she won't mind so much if you fish for a few hours. Oh and one last thing, give her a little extra sugar if you know what I mean on the first night or even right when you first arrive to your place. She'll be glowing and you can pretty much do whatever you want after that! Have fun and good luck!!
Congrats on your graduation as well.
