Expedia told us we had three beds, we had one double. As we thought we had 3 beds we asked the hotel for a fourth bed for a child, four days before we got there and they said fine all ok, just confirm the 4th bed for child on arrival.
The hotel had no note of this when we got there and after half an hour of discussion gave us two extra childrens beds which was better than nothing ! All a bit stressful.
