We go to Nub's from Chicago as our primer for the ski season every year before heading out West. You can almost guarantee great conditions and well groomed runs. 2 days to get your ski legs back with enough diversity on the hills to keep it interesting.
But, this is a skiers hill. The people at Nub's are skiers first, and snowboarders (As a note, not many snowboarders and the ones that do come are just as respectful as the skiers.).
The lodge is roomy enough, and most people don't even use lockers. Just find a corner and plant your bags there. You can unload your vehicle right at the lift, and if you're renting equipment, the rental shop is right there as well.
Good store, but the food isn't great. We usually pack lunches and snacks. But, again, if you're looking for an experience outside of skiing go across the street to Boyne (You can see Boyne from Nub's. They face each other.)
Plenty of very easy LONG runs for beginners. Trails are well marked. My kids learned at Nub's. Now they ski Utah.
Let me repeat again though. Amenities are not what this place is about. Drive up, drop your gear, park, snap in and slide over to the lift. That's the Nub's experience.
