Andrea, the main thing is make sure you have the right safety gear. If they are paddle kayaks, make sure you have paddles leashed to the kayaks incase of a dropped paddle. If you have an old mobile phone, can be handy just keep it in glad sandwhich bags. Rod holders are a must if you are fishing, even to store your rod whilst paddling. If you find hubby really likes kayak fishing, go to a Hobie test day and try a pedal yak. It is a fun way to fish because using a rod and paddle at the same time is tricky. I would run a chain thru the scupper hole and lock to something solid if you are in a caravan park. What kayaks did you get? It can be additive.
