What to do

Im not even new to the milton area but what is there to do for 2 regular adults who dont want to hike? Especially this time of year. I know theres movies. The racetrack. But...there has to be something else? Hidden gems? Google maps and internet search has been zero help unless you know what to search for specifically since all it gives is hiking. Im ok to go out to Oakville and even maybe Mississauga if theres something actually cool. Dont have kids but I'm not opposed to doing "childish" leaning activities. Any recent or updated help would be nice. I know theres a post from about 3years ago for this but. In case things have changed.
