Our family of five, including three youngsters, had a great time. We tent-camped three nights and were amazed at the abscence of mosquitoes (thanks to the bats). The yellow jackets were around but not terribly annoying around our Loop A site. We noticed one camp site in Loop C that was closed off due to a yellow jacket nest being nearby. Yikes! The NPS should do something about this. Last I checked, yellow jackets weren't endangered or anything. There are emerald ash borer traps up in the trees. How about yellow jacket traps!?!?
The proximity to the Visitor's Center and tours cannot be overstated. It's incredibly convienent. The hotel is a musty, damp throwback to a time best forgotten. That said, the AC in the lobby was a welcome relief from the humidity. The restaurants were decent, except the Troglobite, which only accepts cash and has a menu of typical fattening garbage. I'd rather hunt for my lunch in the woods than pay for that junk.
Our family had a wonderful time and the little ones loved the cave tours. Hopefully before we come next time, a new sinkhole will open under the hotel, a new yellow jacket disease will sweep through the park and Obama will be out of office so the sequester-nonsense that ended most of the cave tours (you're telling me Obama couldn't think of anything else to cut in the federal budget?!?!) will pass and services the American people actually want from the federal government (like the full range of cave tours from their NPS rangers) will be reinstated.
