Need a balcony. Life is too short to miss the sunrise in Barcelona while having a coffee in your Frette robe boys and girls. Remember that with the time change, it's hard to get out of your lovely Azamara bed for 7 a.m - you just got to sleep a few "minutes" ago.
Also, you can ask to have any meals served in your cabin. Our balcony neighbours loved dinner on their balcony with white tablecloth etc. We usually had breakfast delivered until we got "climatized' (jet lag always gets me)
Also opening that sliding door - gives the room some fresh air and you're not breathing air conditioning all the time.
It was also very special to watch Stromboli sail by while on the balcony.
