Not just the nightmare that is driving on the M62, it's the cost or parking when you get there!
Not sure what you mean by options; options for train fares or for alternative means of transport? Depends where you live, I suppose. A former colleague lives in Huddersfield and had his job moved to Leeds. He can't use the train because there's no parking at Huddersfield station and he lives the other side of Huddersfield with no decent bus service.
I would guess the best/cheapest option would be a season ticket of some kind. You may get lucky with the price as it's possible you would be deemed to be travelling outside "peak" hours. What are the variables in the 'quotes' you are getting?
