Not really counting if you live in a place like NYC, or if you're walking to the destination (the park, wherever), but if you generally drive to/from places, does your 3 year old use a stroller?

Trying to decide if a double is worth it or I should just use a single stroller and do a) walking 3 year old/ baby in stroller in combo with b) babywearing the baby/ 3 year old occasionally in the stroller.
