If I got the right boats on a web search, these are both 10 ft kayaks with very limited storage. They are wide and beamy so slow speed [guideboatguy has this right, it is more the length but 10 footers tend to come wide and beamy...], and I suspect hatch covers that are challenged at keeping things dry if they get much in the way of wave splash. I presume that you want to end the trip with your relationship to girlfriend intact...
I suggest that you keep it really simple. Drive to a camp spot, with the car holding stuff to assure a comfortable and dry overnight, and paddle around from there. If that goes well then think about more challenging efforts and probably boats better tuned to primitive camping.
