A double airlock would be excessive.

A simple airlock still has two doors, and the inner one only opens if the outer one is closed.

Of course, no matter how many airlocks you have, you can't prevent people from waiting for someone to come in...

1) hapless soul #1 comes in looking for pizza.
2) as inner door opens to let him in, the gang piles into the airlock with pizza in hand.
3) when hapless soul #2 comes along, the inner door closes, the outer door opens to let him in, and he gets stampeded by the departing ex-trapees.

A double airlock merely requires twice as many hapless souls to wander in.
