When setting up Tripadvisor, they will display the room rates to you as if 2 people were booking the rooms at one time. Because of this, the rates for Dorm rooms will appear to be double (twice as much) as what is entered in our system.
In the pictures below, you will see that the rates for the Winter Solace Room are USD 358.00 from Tripadivsor:
Yet, inside of myallocator, the rate for the same room is $179.00 USD
Once your property goes live on TripAdvisor, the rates will be displayed correctly to the customer based on the occupancy that they specify in their search.
