Contact your accommodation provider and the local contact who will give you the keys to organise your arrival in Les 2 Alpes.
In all cases, you will have a contact person on site who will be responsible for welcoming you and making sure your stay goes smoothly. This can be the reception of the residence, a real estate agency, a concierge or directly the owner.
Their contact details are on the booking confirmation you receive by email after validating your online payment.
