Easy 3, it's pretty cake in the lake George Schroon area in winter. The travel distance between the 2 end to end is about 20 mins .Really super easy..
Lake George has more tourist things to do, schroon has nothing but ice and snowmobile trails. There is also a middle ground of Alp Horn Motel it's between the 2 , just to confuse you .. Lol
My wife stayed at the water park last year with grand kids while I stayed at cheap maple leaf (schroon) fishing with friends. I know it wasn't cheap but didn't think it was that outrageous . That's a bit over the top..
Like said I stayed at super 8 downtown Lake George . It was $35. Each for us 2 guys. It's a standard hotel within a mile of the winter carnival and 3 miles to hearthstone campground ( state) where I fish on lake George . If your thinking of sleds, it's not out the door there.
The alp horn ( chestertown) and maple leaf ( schroon ) are, again 20 mins max either way to Lake George .
There really is no worries about reserving way in advance as there is always room at 1 of the 3 and I can throw more in the mix too.
