Having 8 children and not a lot of house we always had two cribs and the baby slept in it until at least 2-3 years old. It saved space for bigger bed until then and was better for a bigger child to sleep in but I did have a porta crib that I used with some until I moved them to the bigger crib in the room with a sister or brother. We didn't have pack 'n plays then but I had a square play pen which is the same only bigger if I needed to take them somewhere ( but not to sleep in ) so actually we used both ideas. I think you'll need a crib in the end but I used a pack 'n play for twin grandsons to sleep in at my house and it worked but if for a long time it's not very padded or comfortable looking. The top for infants seemed to dip in and I, personally, didn't think it very good compared to a plain bassinet or porta crib.
