Whichever you choose, go ahead and do it. My wife and I were full timers for 5 years and there were many times I would have loved to have a Kayak so I could try out some real fishy looking waters.
There are a number of active kayakers on here so you should get some good input. The only advice I have is to get a sit on top model. I bought a sit in type for my grandkids and it is hard to get in and out of from the dam of the pond in their neighborhood. A sit on top would have been much better.
