Acute Care clinicals

For all those ACNP's out there, I am about to start my first clinical rotations and was wondering if any one has any suggestions as to where I should go? I eventually want to end up in the ER where I have spent most of my nursing career. I was thinking a hospitalist preceptor might be beneficial, although I can't see myself doing this as an NP. I am also interested in interventional cardiology, has anyone ended up going into this area? Thanks for the advice, Moe.
