Adirondak Trailways has a bus that leaves from Albany daily at 1:50pm. The ride is about 4 hours to Lake Placid. It's $64 roundtrip.
This is a good site to search lodgings,

In town, the Northwoods Inn is nothing special, but very close to the rink, right on Main Street and you can get a room for around $112 per night. Also, Art Devlins is worth looking into. A very clean motel, about a 7 minute walk to the rink and usually one of the least expensive in the areas. I know there's more motels outside of town, but if you don't have a car, I would suggest calling them and making sure they are on the trolley route.
