Creatures & Creators Night Market turns the Houston Interactive Aquarium grounds into an unusual after-dark shopping stop on two October Saturdays. Local makers and food vendors set up indoors and outside, while a live DJ and cash bar keep the energy going after regular aquarium hours. Families can browse the market early, add animal encounters with a separate aquarium wristband, or stay into the evening when market admission becomes $5 after 8 p.m.
