    So, DH and I both tested negative today and now I can finally get excited about my "Saturday Cruise" on the Magic.  It's been, I guess, 3 years since I sailed Carnival and I need a "Casino Basics Refresher Course".

     

    I know that I need the pin# (birth date and month?) to charge to my cabin and use OBC.  Right?

     

    When I cash out...do I print a ticket or do I upload to my S&S card?  Memory says "upload"...but is there an option?

     

     

    You will set your 4 digit pin and your memory has not failed you - your play will be upload to your card. Have fun!!

    To us, there are several that make the cruise more enjoyable.  Dr. E, in particular, is one that would make us book a cruise on a ship that he is on just because he is the CD.

    LOVE Dr. E!  "Good morning...I said good morning..."

    My God, you come up with some ideas.

     

    1.  The chilled water does not reach 70*F when it returns to the chiller.  It is about 55*F, which is the beauty of a closed system, you can move enough water that the delta temperature never gets too high.  Remember, the air supplied (either through the fresh air coolers, or the cabin coolers, is not 70*F, it is colder than that, in order to cool the room down, so if the supplied air is not 70*, the chilled water isn't.

     

    2.  Where is this 200 meter hose stored when the ship is in less than 200 meters of water? Is it rolled up on a drum?  Where is this drum?  Under the ship?  In a tunnel in the bottom of the ship?  How much drag is that?  Or is it brought back into the ship to a reel through some sort of seal, that is capable of sealing around the hose, but is also capable of passing the required flanges (because a bolted flange would be the only safe method of joining hose of that size, and that length, under that stress)?

     

    3.  When the ship is in shallow water, and there is no cold water to pump up, how does the AC work?

     

    4.  The refrigeration cycle uses evaporation and condensing of a refrigerant to cool the chilled water, and since there is always some "latent heat of evaporation" when a substance changes from liquid to gas (evaporation) (latent heat of evaporation is the amount of heat needed to change an amount of refrigerant (or water) from liquid to vapor without changing its temperature), the heat that is absorbed from the chilled water by a ton of refrigerant flashing from liquid to gas is far more than what a simple water/water heat exchange by one ton of cold sea water could do.

     

    5.  What size hose were you envisioning?  Cause it would need to be a 16" diameter hose, at a minimum, and 200 meters long?  Your talking about 7-8 tons of just the hose, plus the water inside it, since you're dragging that along with you, which would be around another 25 tons.

     

    While geothermal heating and cooling is efficient on land (it ain't moving), it is again a closed system, unlike your idea of an open system taking cold water and discharging it after it has cooled the chill water.  Any closed system is more efficient than an open system.

    You are just THE BEST!

  4. Hello - I will be on the Carnival Celebration on Nov 6th, from Southampton to Miami. 1st time in the UK and 1st Transatlantic. What are the differences, if any, for a ship leaving UK/Europe vs. US? I saw a post referencing different alcohol policies in terms of what you can bring on board (I haven't vetted this info) so am curious as to what may be different. I am looking into the UK COVID testing requirements as well to make sure all the bases are covered. I appreciate any insight the seasoned TA travelers can impart.
