Hi. I am sailing with my granddaughters, 17 and 7. They saw a fish extender video on YouTube and have been so excited, I think we are too late so I am going to do it myself and every night drop a small surprise in. And because they want to give gifts too I will bring some stateroom gifts. I wish we had found out sooner. This is our 2nd cruise but 1st 7 night. Also my first time sailing with the grandkids alone. So excited.
