I'm starting a a diploma school in Jan although I will be in the last class for which the diploma program will be open. Starting the following semester the school is switching to an ADN program (I think in response to pressure to offer at least a degree of some sort).
At first I was skeptical about only receiving a diploma but since I already have a previous university degree I tried to keep in mind that the goal is to get my RN as quickly as possible and not about the letters after my name

If I choose to go back to school after I'm done I'll most likely take the RN-MSN or some other similar route.
The program I'm entering is hospital-based so there is definitely more emphasis and access to the clinical portions of the program. I'm looking forward to immersing myself in the practical aspects of nursing as opposed to the theoretical.
I would say that the process of getting admitted to an diploma program is much quicker than and ADN or otherwise. Mainly because most people don't think to look for diploma programs and therefore there is less competition. In my case, I think cost was also a limiting factor for many people. The program is a private one and tuition over 4 semesters will run over $20K. Nevertheless, I'm just happy to be in a program and am looking forward to starting and finishing much earlier than my peers at the local community colleges who are still waiting to get in even though we have the same prereqs etc.
In the end...no matter where you go the most important thing is that you come out with an RN (hopefully!).
