A friend of mine used a nylon bag, usually used to hold a bunch of basketballs, as a live net and never seemed to have any problems with it. I'm sure with your ingenuity that you could set it up to work with your toon.
I've also had a CO give me a break for not having my licence with me. He called it in and found that I had a licence and told me to enjoy the rest of the day. I don't know how many times they would allow this to happen, but I haven't been asked again. My licence is always with me just in case.
You can arrange fishing trips from the chaps hanging around every pool at the resort if you wish and they will take you out. I didn't bother when I was there, but it is an option. PS remember the sign on the toilet means you can't put toilet paper in the toilet. It must be collected in the waste paper container provided.
