Adult degree completion?

I'm a full time working mom that needs to complete a degree in Accounting or Management to be considered for a promotion. I've read tons of neg comments on online degree completion. I live in the KC metro area. Any suggestions? Tuition, convenience, completion time, and outside work are huge considerations. I've searched and searched but haven't found a clear "winner". Any input would be greatly appreciated! I currently work for a large corporation as a Credit Administrator and looking towards Credit Management. Thank you!!
