I responded in another post but here is the lowdown on the "secret" doors. There are no secret doors, period. There are exit doors located forward on the Lido and Empress deck (that I know of) that lead out to a small observation deck where passengers like to take photos when entering or leaving a port. There are no chairs on this deck and it is dark at night. There are staterooms located facing out on this deck. We were in one of these staterooms on our last cruise and people were constantly banging on our windows and trying to peek in.
