I would just enjoy that area by the pool with a beer and do a dedicated trip somewhere else. Im just south of phuket at the end of August for a wedding but taking a few days to fish with bkkfishingtours for wild giant snakehead on fly north of bangkok. Flights within thailand are crazy cheap and the 2 days fishing is well priced too. You could look at something like that or a jungle stream trip chasing mahseer which is what I originally wanted to do (bloody wet season killed that idea!)
