Co-sleeping complement

Megan
So, we plan to co-sleep, which I assume is the semi-norm in this group. 
I'd like a side-sleeper, because the blanket my sweetheart uses is a fluffy comforter. It seems like a good option for us. 
So, I'd like your opinions on a question:
a) is there any reason to not get a pack and play that has the bassinet option? I'd love to wear the baby for naps, etc etc but it won't hurt to be able to put them somewhere safe and portably so when needed/able. Particularly as we have dogs- super sweet, good with kids of all sizes, dogs, but I still want the option to keep them apart. So basically, any argument against pack and plays?
We may get a side-sleeper and a pack and play, if we can do so affordably.
