Depends on where your staying. The bus runs a lot so there are plenty of times to get up there and leave.
But there is not many places to stash stuff. Parking has been a pain the last 3 years so if the Cottonwood's are closed then it's almost impossible to get up to Basin.
If your taking a Carving board it can get chaotic with the number of people up there so I take two boards. One for the morning then one for later.
Hope this helps.
