Pros: Proximity to Burlington, Price, Terrain
Cons: Needs a refresh
If you live in or are staying in the Burlington area, Bolton is only 30min away. For perspective: Stowe, Mad River Glen and Sugarbush are about 1 hour (half interstate travel). Smuggler's Notch is 1 hour (no interstate, lots of town, slow route 15). Jay Peak and Whiteface are 2 hours away, long and complicated.
The road up to Bolton is a four mile, fairly steep climb. It has two parking areas that are pretty close to lifts compared to other resorts in the area.
From a low intermediate perspective, the availability of short, gentle runs is very nice. Width is good enough to avoid fear of trees, and available intro blues are very accessible. Two low/mid mountain lifts allow quick access to easy terrain while two full mountain quads and a double access the rest. I can't comment on the expert terrain and glades/woods runs, but my coworkers and friends that can usually rate it as pretty good (probably has high a praise as you'll get from these Mad River junkies).
The place needs a bit of paving work, and the facilities could use an update, but overall it's your perfect, value oriented mid size resort. It also offers the only night skiing in the area -- great for an after work session Wed though Sat.
It has the usual bar, a cafeteria and a wood fired pizza (very good, reasonably priced) area, but for nightlife you will need to drive the half hour into Burlington.
