My greatest suggestion is for you to think about a place that:
Makes you feel at home
Reminds you of your love story
This answer can be a park you frequent for walks. This can mean going miniature golfing. This can mean sitting on the floor of your kitchen. There is no right answer here. You can also just have a place you find beautiful and you want your photos there.
But the key thing I will tell you where you are isn’t going to be the highlight of your pictures, it is going to be you and your fiance. It is going to be your love and life shining through no matter where you are.
Feel free to consult your photographer on the places you are choosing between but I will tell you over and over I have found you can find great ways to shoot almost anywhere: make it someplace that means something to you!
Once you have your location ahead of time think about areas you would like to have photos taken, possible looks you like.
I personally like to scope out the location before the photoshoot for this same reason, to be prepared for ideas and what’s next but depending on your photographer you might be better off prepared for yourself to get the most from your session.
