We have the arm's reach mini. It was great for naps, or for me to roll our son into after he fell asleep if I needed to get up to pee. It was also WAY easier to take to my parents' house if we were staying over than the huge packnplay. He wasn't keen on falling asleep in it, but it was great to have a safe place to put him down after he nodded off. My son needed 7 stitches after rolling out of my brother's bed (awake) with supervision at 6 months old, so I'm not a fan of the pillow fort while you step out of the room idea, both from that experience and from seeing how easy it is for babies to crawl under them. For the most part we bedshare, with a crib handy for naps or if my husband and I want some privacy once he's asleep. I second the chest sleeping the first few weeks. There was no place else that either of us wanted to be, and I sleep pretty lightly whether he's in our bed or next to it, so I wasn't worried about smushing him. Husband is a deep sleeper and would totally pull the covers over our son's head if I didn't prevent it. A blanket for everyone can work well.
(My poor brother still gets teased "I left him alone with his Uncle for 5 minutes and we ended up in the emergency room for 3 hours!")
