Yes, indeed! Kept the balcony door closed. So glad to hear you had no issues. I didn't think it was an issue to register a comment. I am planning a cruise to Cozumel in April, and this time will be sure to make a request to have the thermostat looked at (with a smile, graciously, and appropriately) if it does not work.
Thanks for your input, and Happy Cruising! If you feel comfortable sharing, when are you next cruising!!
