Yes. The ones at the Dickey Ridge visitors center are open. Full "comfort stations" facilities with running water and lights. There are several pit-toilets around (like at the Elk Wallow picnic area. The full toilets at the Elk Wallow shop are closed, just like the shop). And the toilets by the Thoron Gap entrance were open. Sinks, toilets, lights, etc. We were there last weekend. I'm sure the rangers at the enterances have more info. But make sure you grab a map! Your cell service (and internet data) may not be available when you really need it.
Yea. Multiple.
when we were driving in the sky drive area there was a place where we stopped, had bathroom facilities.
