RE: pack n play- canopy and vibrating bassinet necessary features?
Our pack n play has a 3/4 bassinet, and a changing table, but no canopy or vibration feature. Honestly, I don't plan on taking the pack and play outdoors, thus I didn't see the need for the canopy. And, both our other bassinet and bouncy seat have vibration features which my son couldn't stand, so I've never used them for more than a few seconds.
I'd skip those features, particularly the vibration feature, unless you're really set on it.
