I have no idea what the bull shark season is, but I’ve done the Bats dive 5 times over 3 years and saw lots of bull sharks on all but the first dive. All during August.I was there in end of August. Bull shark season is from NOV - MAY.
It is in Gunacaste. There are multiple "cities" where to stay. I stayed in Tamarindo, but that was an hour drive everyday. If I go back I would probably stay closer to the dive shop and avoid the drive. Though Tamarindo has a lot to offer in bars and restaurants and also good surf spots.
