The requirements for documents needed at check-in depend on the type of accommodation and the applicable regulations. For hotels and other accommodation facilities, a Russian passport, an international passport, or a driver’s license may be accepted. For apartments, serviced apartments, and other properties where check-in or contract conclusion is carried out according to the rules of a specific property, the required documents are determined by the property itself. Know Before You Go • If you require a visa to enter the country, your property may be able to help with the supporting documents needed to obtain one. To learn more, you can reach out to the property via the contact details included on your booking confirmation. The property may charge for this assistance, even if you end up cancelling your reservation. All arrangements are solely between the property and yourself. Russian citizens: Adults (aged 14 and over) must present a valid internal passport at check-in (international Russian passports and driver's licenses are not accepted). Birth certificates must be presented for all Russian children (aged under 14) at check-in. If a Russian relative or legal guardian (rather than a parent) is traveling in Russia with a child under 14, that relative or legal guardian is also required to present documentation certifying authority to accompany child at check-in. Foreign citizens: Adults and children must present a valid passport, visa, and migration card at check-in.• The seasonal pool will be open from May to September.
