This is what you're used to seeing in terms of a pack 'n play but it's a bit smaller.  Thus it works for smaller infants / young toddlers who need more confined space / still sleep in a bassinet / haven't transitioned to crib.  Perhaps you're also staying in a small room within your AirBnB and you don't have the room for a larger pack n' play or crib! For reference:

• Stage 1 Bassinet: for use up to 15lbs
• Stage 2 Bassinet: for use up to 20 lbs
• Stage 3 Playard for use up to 35"
