In a frank discussion with one of the hotshot professors, he said that the department had decided to concentrate its efforts in recruiting for professors and marketing in what they considered the school's key strengths: environmental planning, transportation planning, and urban design.
There are plenty students who come to Penn with no background experience in design (or planning) and who lack even basic design skills. Penn offers a certificate of urban design (check it out, it is somewhere on the website), and between you and me, while it is required to formally apply for the certificate it doesn't take much to gain acceptance (a nicely written essay describing your passion). The certificate classes offer you the opportunity to take extra design classes and it is doable within the two year degree. The general degree requires you to take at least 19 classes, of which 4 may be taken outside the department, so those four can be design classes.Disclaimer: if you come to Penn, be aware that you are allowed to take a number of classes in architecture and landscape architecture and even in other departments (engineering, for example, offers several planning/design relevant classes). Most people, including me, weren't fully aware of the potential classes outside the department.
I came pretty much straight out of college as did a whopping number of my classmates in my year, so it doesn't hurt you as long as your record is good enough to past muster. But, looking back it seems that it would have been more valuable to have had two or so years of work experience, of any type. It helps when looking for post-graduation jobs, and it would have been useful for me to have explored the field more closely before pursuing a master's of city planning. If I could turn the clock back I would have applied to landscape architecture programs, not city planning. A lot of what planners used to do, such as site planning, are now being done by landscape architects. But I made the choice and must live with the consequences.
If you wish to do urban design, look closely at the course offerings and email as many professors as you can for their views on the subject. You may find that you would be better off pursuing an architecture degree with an urban design focus rather than planning/urban design, depending on your personal interests.
