I spoke with the doula, and it really cleared a lot up so I feel much more comfortable about her.
I spoke with the OBs at my practice, and they are very supportive of my preferences. One was hesitant about me saying I don't want an induction, because she wanted me to be aware that some circumstances may require induction. I agreed that my plan was absolutely flexible depending on baby's needs.
Also took a tour of the hospital, and it seems the nursing staff and hospital is supportive of natural birth and of many of my preferences--they even provide birthing ball, bar and stool!
Thanks again for your feedback!

DH and I took the hypnobirthing course, which I was very happy with. I've been very excited about it, practicing daily, etc.
Several months back, I hired a doula. She is not trained in hypnobirthing, which I was fine with, as I'm comfortable with my and DH's ability to help me stay focused. I hired a doula to help advocate for me, as I'm having a hospital birth and wanted some extra support.
We met with the doula for the first time since I hired her months ago to go over preferences/birth plan/etc. She was much more negative than she had been when I hired her. She kept talking about the things I wanted in my birth plan (freedom to labor and birth in positions most comfortable to me, room as dim and quiet as possible, breathing the baby down/pushing only when I feel the urge and not when directed, etc.) as not being likely to be honored in the hospital. This has really been bothering me.
Is it really unlikely that the OBs and nurses will not respect my wishes and birth plan? I probably should have hired a doula knowledgeable about hypnobirthing, but since the contract is signed and payment made, I can't change that decision now.
Any suggestions, thoughts or advice?

Re: Update: hypnobirth/doula/birth plan questions
As a doula myself I can understand where she's coming from. Sometimes a client's wishes aren't realistic given their care provider or birth location and we want our clients to be prepared to encounter resistance.
Sounds like her ways of conveying that to you could use a little finesse though. Is she suggesting alternatives or ideas to help you get what you want?
Just an FYI...doulas cannot advocate on your behalf. We are there to support you but almost all of the training/certifying organizations make it very clear that we are not advocates.

It's possible that she's referring to this particular practice/hospital, but she said she has not attended a birth at this hospital, so it wouldn't be from personal experience if she was.
I'll be talking with my doc about my preferences at my next appointment. If they seem really close minded and not open to discussing my preferences, I plan to look into transferring to the midwifery practice that just started here.
As for advocating, I just meant that she could provide me with more information, education and support when I'm approached make decisions in the hospital. I definitely phrased that wrong in the first post
I think I'll contact her tomorrow too talk to her more about hypnobirthing. I can't imagine she would be opposed to learning more about it so she can best support me.
Honestly, some of the things your doula is complaining about are not that radical in a hospital setting. Some even depend on the nurse you have. I know that my nurse let me labor down before calling the OB in. Also when I moved to the bed to start pushing (I labored in the tub) I got into the position I wanted. No one told me to move and if they did I would not have unless their was a medical need. I would speak with your provider and feel them out about the situation.
