registering at another hospital ?

Hey guys! So I was curious about something. I already preregistered at a hospital, months ago. But I've had 2 emergency visits there already and both experiences where pretty bleh. With staff and all. Ive also had a couple people come up to me and tell me that this hospital is pretty bad when it comes to labor and delivery. I've kind of changed my mind about giving birth there, my ob/gyn works at 2 different hospital locations and I was thinking maybe I should try the other location but I was wondering if it's possible to be preregistered at 2 diff. Hospitals ? Or if I should just stick with the first hospital
