I booked a room from the hotel website for my family for 2 adults and one child and I requested an additional bed for my 5-year-old son. When I arrived, there was no additional bed and when I requested one, I was asked to pay $80 extra. Never anywhere in the world, I have been asked to pay extra for an additional bed for my child. Every hotel is transparent about the price of the room when it is booked, however, The Hyatt Hotel with its strategy of hidden costs to get as much money as possible from customers is very disappointing :(
First and last stay in Hyatt Canberra.
