If it is what you want, GO FOR IT!!!
Just make sure that the orientation is adequate (12 weeks or so 1:1 with a preceptor.) Also make sure that you will have adequate back-up from experienced nurses and a mentor on the shift to which you will be assigned after orientation.
If you ever tire of L&D, you will have a multitude of skills that you can take to almost any area of nursing: OR, PACU, Same day surgery, Nursery, Mother-Baby, Post-partum, Med-surg, OB office, Home care, etc.
Since you are considering 2 units from the same hospital system, you could ask the recruiter to set up a shadow day with each unit. That may help you to decide, but again, if L&D is what you want, GO FOR IT!!
Good luck in your new career!
