If you have 2+ kids, how do you handle going to crowded places like fairs?

I take the kids many places myself...if its outside like a fair , the zoo or Adventureland I take my triple stroller or my wagon...If I have to go to the mall I take the double and one walks....it all depends on the kid...some kids dont want any part of being in a stroller so that will make it harder for the parent....
