If you were able to score a 660+ on the GMAT or better and bring everything to the table in your application (essays, EC's, rec letters, etc) I think you have a great shot at both. Part-time programs are generally easier to get into b/c they draw from smaller applicant pools within approx a 200 mile radius of the schools (as opposed to everywhere in the country). Also, the part time program rankings are actually different:

Good luck!
