On the drop-off day, you do not need to bother your head so much because the Nanny knows you are coming and will be expecting you.
When you meet your Nanny, make sure you have your booking confirmation email, booking reference,SMS confirmation and / or valid ID showing the name of the person delivering the luggage and picking it up.
It is also possible for someone else to pick up your luggage for you. You just have to fill in the identity of the person in the fields indicated at the time of booking. The person has to show his ID in order be able to drop the luggage and the same ID will be asked before picking-up the luggage.
We proceed this way to make sure all the luggage dropped-off and picked up is done by the rightful owners
