Taking a trip with my mom and brother to Key West this February. We are staying at Parrot Key Resort. My brother loves to fish and would like to go deep sea fishing. Wondering if we should rent our own boat or go with a tour. Thoughts? Also, any other recommendations for the trip? It's kind of a "cancer break" trip for us as my brother has been diagnosed with stage 4 prostate cancer and just wants to get away from it all.
