The key to success seems to be going to places with an hr drive so that i 3 yr old get a car snooze and we can (hopefully) avoid meltdown at the museum. That and you need to give the older kids more autonomy. I stick with the 3 yr old and let the 8 and 10 yr old go off on their own as long as they stay on the same level I’m on or within certain exhibits.
OP here. We recently got a membership to the Maryland Science Center. I think Port Discovery, the aquarium, Richmond Science Museum, Franklin Institute and the Please Touch Museum in Philadelphia would be ok with the 3 kids.
