Occupancy discussions are limited to this thread:
DVC Occupancy where you may continue the discussion if you wish.
Occupancy for studios is 4 plus a child under 3 in a Pack N Play.
DVC is currently allowing 5 of any age in a one bedroom unit, and AKV non-value class units, as well as BLT units have sleeping accommodations for 5 in the one bedroom (king bed, queen sleep sofa, and an additional sleeper chair.) For other DVCs you'll need to provide a sleeping bag or air mattress.
DVC Membership, or any timeshare for that matter, doesn't fit neatly into everyones budget, family size and travel habits. If you can not comfortably live within the rules agreements, a timeshare may not be the best option for you.
