We stayed at AKV last June in a one-bedroom. We did have 5 adults and a baby (5-months) with us. Dh and I in the bedrooms, Daughter on sleeper chair, Son and DL on couch, baby in pack in play. DH and I had plenty of room. No one else complained of space. Youngest Daughter could have stayed with different family member as we had 3 other studios but choose to stay with us.
If everyone is close family it works out well.
