We booked the room of 2 alduts, when we checked in with 2 alduts and 2 childs, firstly they requested us to book another room for my kids, and we rejected as our kids cannot stay in a separate room. Then they requested us to pay extra bed for my big kid (11 years old) even when we did not need that extra bed (we said we can manage with the bed sofa in the room). Normally hotels only charge extra fee for breakfirst in this case but they just kept saying "the rule here is just like this".
