I was there for the day only, so I only did the Miraflores Locks and Ancon Hill. That's pretty much all my personal recommendations....
Oh, and Pita Land. Best. Burger. Ever.
Tell them to download the Kosher PTY app, tons of restaurants that deliver and can see all the restaurants from your phone. I'm gonna stay in Panama City which I think is a better bet. We're gonna also go to the locks, canal and Monkey island in the canal, a tour to see the Embrera Indian Villages and also Casco Viejo (the old city) is supposed to be cool. We're not going to San Blas, coffee growing Highlands, Ziplining and a bunch of other stuff because of our kids, but there is ton to do!
