The basic rate plan list is divided into the Rates and Supplements sections. Usually, at the end of the rate plan, a list of promotional offers is included which may apply to the basic rates. If a hotel establishes use conditions that apply to all rate plans they are repeated in the booking rules for each rate plan. A common case of use conditions is the requirement of a minimum stay length.

Price type - one of the basic attributes for rate plan is ChargeType. It offers the following values:

• 12 (once) per stay
• 1 (once) daily
• 17 (once) weekly
• 18 per room per stay
• 19 per room per night
• 20 per person per stay
• 21 per person per night
• 50 Per room per week
• 51 Per person per week

For the one Rate Plan, there could be different ChargeType for basic and supplements prices.

BookingRules are used to specify certain conditions that must be met in order to qualify for these rates.

• FixedLOS exact stay duration required
• MinLOS minimum stay duration
• MaxLOS maximum stay duration

Time and TimeUnit define the value of the LOS (eg. 1 week, 12 days, etc.)

Supplements for additional pax (3rd adult, 1st child, 2nd child etc.) are defined in Supplement elements with a SupplementType=”Pax”. The pax types referred to are defined by their respective age ranges. The no. of the additional pax of each pax type is specified in the AdditionalGuestNumber attribute. If AdditionalGuestNumber is not specified the supplement applies to all pax of the specified type (adults, child, any, etc.).

Type of pax is defined in the AgeQualifyingCode attribute. It offers the following values:

• 10 - refers to adults
• 8 - refers to children
• 7 - refers to infants

The supplement can be specified as a percentage value that applies to the basic rate or an amount which replaces the basic rate. In cases where an amount must be added to the basic rate, the attribute AddToBasicRate is set to “true” (otherwise it is assumed to substitute the basic rate).

    Ex.: <Supplement SupplementType="Pax" AdditionalGuestNumber="2" MinAge="16" Amount="60.00" CurrencyCode="EUR"/>
         “2nd additional adult pays 60€”
    Ex.: <Supplement SupplementType="Pax" AdditionalGuestNumber="1" MinAge="2" MaxAge="15" Percent="-40.00"/>
         “1st child gets a 40% reduction on (pays 60% of) the basic rate”
    Ex.: <Supplement SupplementType="Pax" AdditionalGuestNumber="2" MinAge="18" Amount="-20.00" CurrencyCode="EUR" AddToBasicRate="true"/>
         “2nd additional adult pays 20€ less than basic rate”
    Ex: <Supplement MandatoryIndicator="true" AddToBasicRate="true" CurrencyCode="EUR" Amount="7.00" AgeQualifyingCode="10" InvType="Extra" InvCode="EX20" ChargeType="21" End="2020-10-31" Start="2020-06-01" SupplementType="Extra"/>
