If it were me id hire a guide for 1/2 or full day. For what you'd pay for a rental boat and not knowing anything about the area, a guide will put you on the fish immediately, all day long. Plus youll probably learn some new tactics.
There is one guide i know of, because I wanted to hire him to fish and learn the Delta, his name is Bobby Barrack. Look him up on line. He's not only a guide he's an instructor, teacher. He's pretty busy as most good guides are, so I'd contact him ASAP or when your other plans are solid.
Good luck and great fishing to you.
