I know it says that you are able to take a 12x12x12 cooler on the ship but I was curious as to how you all packed them.  Do you pack the collabsible coolers in ur luggage along with the beverages you're bringing or do you use it as a carry-on?  Any advice on this would be a great deal of help.

Are you sure on that size?  I was thinking about getting one with wheels not like a big beach one, but one that I could still pull that way I could put my wine and soda in it.  If someone knows the size for sure please let me know and if the 12x12x12 is correct let me know that too....thanks!

Large cooler restrictions:

Carnival Cruise Lines does not allow guests to bring large coolers on board its ships. However for purposes of housing small, personal-sized coolers no larger than 12” x 12” x 12” for the purpose of housing small quantities of non-alcoholic beverages and/or medications are permitted as carry-on luggage. Screening and movement of large coolers through embarkation is an impediment to the boarding and security screening process. Therefore, large coolers are not permitted as carry-on or checked luggage.

Poorly constructed, but yes 12x12x12 is it

Well thank you for letting me know.

I see you are still waiting on your 10th...you should pick up one of these cheap cruises just so you can get your 10th.  The Sept. 12 out of Mobile is only 199.00!!

Do you just carry your wine in your carry on cooler or what?  Also can you take a corkscrew on with you?  Should I pack this in the carry on cooler as well?

I carry the wine on with me in a wine bag and put the wine opener in my suitcase.
