Is 3 hours enough time to see the show? HELL NO! But then again depends on what you want to see. Friday the floor traffic is not as high and there are the tec seminars. So, that may be enough time to check out a couple of things, see a presentation and grab a cold one at the Tec Party. Saturday, a lot more time, a lot more people. It all depends on what you want to see.
