So I had some vacation time open up suddenly, seeing if I can get a last minute deal for Galapagos liveaboard. I know it's whale shark season there, but honestly I'm not too interested in seeing them. I'm more interested in seeing hammerheads (which I believe the best time is in May/June?), rays, large schools of fish, penguins?, dolphins, etc. Would Sept/Oct still be a decent time to see those or would you recommend waiting until spring/summer? Thanks!
