My dad turns 60 this August and my brother and I would like to take him on a fishing trip somewhere in Mexico as a gift. We are probably looking at a 5 day/4 night deal. We want to get into some great fishing, have a good time relaxing together, avoid the tourist zones, and keep the cost more or less reasonable. I've looked online and find numerous package deals, but very little feedback regarding people's experiences. Any guidance or suggestions is greatly appreciated.
