Just to clarify for the OP and others posting here who have only stayed at AI resorts in the DR, there are definitely great non-AI options around the Bayahibe/Dominicus area, and it is a very safe area to stay. Many travel here to stay in or near the villages to experience life here, and are here to take advantage of the excellent fishing and snorkeling options out of Bayahibe.
As far as RCI-affiliated options in the area all I know of are AI, but you often can get better deals by not using RCI.
