It is imperative that you contact the person in charge of your arrival at Les 2 Alpes a few days before your stay to make arrangements. Late arrivals are accepted with the explicit agreement of the accommodation provider. They can therefore be refused without this justifying a reason for cancellation on the part of the client. (You will find the contact details on your booking confirmation).
In all cases, it is advisable to enquire before arrival about the possibility of a late arrival and the arrangements for this.
If you are planning to arrive late, please make a request in advance. In general, hotels accept this type of arrival more easily than flat stays, but you should always ask your accommodation provider to confirm this point.
