I am cruising next year to So. Caribbean and have never had a balcony room before. I was telling a girlfriend that I cant wait to hear the waves at night and she scolded me! She said it was too hot to leave the balcony door open. Then I realized she was saying this because it is a gripe for her. Apparently, it messes up the airconditioning in the other rooms. Is this a common gripe? I will not keep the door open all night, but it would be nice to feel the warm breeze in my room for a little while. Opinions on this are welcome!!
