The walk is easy, near major highway is raised so no problem crossing underneath it.

45 mins, maybe an hour. Depends if you have little ones really.

Perot does have paid parking, but for a lower rate, park on the other side of the freeway under the bridge. You have to walk a short distance but the parking rate is much better.

Yes you can walk easily to your destination. I think walking allows you to notice the flavor of Dallas.

If they love dinosaurs then I would definitely do it. If they are not that into dinosaurs then don't. There is a lot to do and see there whether you see the dinosaurs or not.

I have not seen the exhibit. Am always up for more dinos with kids that age. Hopefully someone can answer that has seen the exhibit!

Hola Liliana, lastimosamente miestras entuve en TX no me quedo tiempo de ir al de Houston, pero te aseguro que no te arrependiras de ir al de Dallas. Ve muy comoda por que se camina mucho en sus 5 niveles. Saluditos!!

Yes. It's outdoor parking under the highway.

Depends on what you are interested in. We spent 4hrs there but went to a movie too..I found the exhibition on birds very interesting and could have spent more time there. If you don't want to do interactive activities it will take considerably less time. if you are not much interested in particular ares you ca skip them. Ask yousrelf why you are going. Is it worthwhile just to run through?
