Length of stay has to be provided for the Rate Plans with LOS enabled.
Explanation and EQC partner Action:
The message didn’t include the Rate/@lengthOfStay attribute for a rate plan that is length of stay pricing enabled. Review your implementation of Expedia QuickConnect and make sure the pricing model you use is in line with what is configured on the HotelExtranet for your property.
