I wanted a homebirth, but didn't feel like it was possible, so I did everything to ensure a fulfilling hospital birth--took Bradley classes, had a doula, had a great birth plan, only went to the hospital for the final couple hours of my labor, etc. I had a "successful" unmedicated hospital birth, but the bottom line was that I didn't have a homebirth, and I realized *after* the fact that in my heart, that's what I really wanted.
I notice that you say that you're, "probably going to have to birth in the hospital." If you want a hospital birth, that's great. But my one piece of advice is to not settle for something you don't want when it comes to your birth.
