Hi, I am glad you are not intimidated by this board. It gets a bit "noisy" at times.
I did this same cruise with Costa in February and had a great time.
Yes there is a sign and sail card. It will be waiting for you in your cabin. You must at some time during the cruise go to the desk and hook it up with your credit or debit card. I suggest doing thisat an "off time" as I have heard others complain about waiting in line. We never had this problem,guess we were lucky.
The cabin tended to be a bit warm. We complained and it was fixed in a timely manner.Our dining mates werenot satisfied with the temp at all and continued to complain and were given a balcony cabin!!!!! I was impressed!
I don't know about the beer,I brought some Irish Mist in a mouthwash bottle(a hint from an experienced cruiser or should I say boozer......
) We wanted Diet Coke so we bought it at Key West and carried it aboard without any problems. I suppose you could pack it in your suitcase if you think the cans won't rupture(if you are flying).
We used the snorkle equipment provided on the excursion we went on. It seemed satisfactory.Can't help you here.sorry!
At Key West you will dock at a military yard,so they will shuttle you to town and there is plenty to do on foot.
At Progreso,there is a five mile pier,there is also a shuttle to the end . We went on an excursion here so we didn't see much of the town. There is a beach on either side of the pier.Water was murky when we were there. There are taxis available if you want to go somewhere else. There is a largeshopping plaza right on the pier. You can haggle well here,it's fun.
In Cozumel we docked south of the main city. We took a taxi to it. It was $6 ,and we shared the taxi with a cruise member from another ship. You have plenty of places to shop and eat. You can also get a taxi to one of the many beaches.
Go to google or some other search engine and type in each port and you will get more info than you know what to do with.
In Grand caymen the ship is not docked but must stay out in the harbor due to restrictions. You will go to Georgetown on a launch and there is tons of stuff to do.
There is a restaraunt within walking distance called the paridise something or other,and you can snorkle right there.
We did not go to the ship till after 3:30pm and boarded within 20 minutes. You as Canadiens will probably have to check in extra so it may be longer for you. If you go early at 1pm you risk the huge crowd.
You will have lots of folks to chat with as there are many French on board.
I hope this has been helpful and I wish you and yours a grand time. Rosie
