I need to find the quickest and cheapest way from Campbell Park coachway Milton Keynes to the hospital?

Going to be dropped off by a long haul Bus service at The Interim Coachway Campbell Park MK and i need to get from there to the Hospital Asap... Cost is of importance also... Anyone know of any direct bus services or if its possible to walk it in good time? Taxi prices as a last option. Cheers.
