Hi Shannon. I am new on here as well so I am not sure what we are able to post or not. I will tell you I have been to both islands and both were beautiful. Be prepared that Kaui is very mellow very peaceful and just a perfect place to relax. Oahu is more upbeat and has an area where its pretty much like a major city, shopping, very busy but nice. I have a cousin who lives on Kaui and is a wedding photographer. I am not sure if I can post her website so if you are interested in a photographer private message me. Other than that I cant help with anything else. Lots of luck with your planning.
