Hey, I was wondering if someone could give me an advice.

Some friends and me are going to netherlands-belgium-luxembourg this summer. The thing is, our trip takes us to Prague first, where we have a 4 hour stop, we'll be on the airport waiting for our connection flight.

I was wondering if anyone knows: are 4 hours enough to get out of the airport, reach Prague itself and quickly visit some attraction points and then return to the airport on time to catch our connection flight, or is it just too big a risk and not worth taking (we could miss our connection flight if we're late).

So, does anyone know? Preferably someone who has been through Prague.

Thank you :-)
