Where are fun places for 12 year old boys and girls to go?

You can take them to a clothing shop like Hollister, Aeropostale, Playto's Closet, American Eagle, or Belt Buckle. Maybe if they like to do Arts and Crafts take them to a beading store for earrings necklaces or bracelets. If you want to just have a fun day with them then take them to fort fun water world or elitch gardens. Considering the money situation take them swimming at a neighbor hood pool if none put a sprinkler and play in it with your kids. You could make snacks to have it a fun long lasting day. So consider each of these and if none fit then make up your own.
