Hello there! We are from Hobbs New Mexico...only about 6 hours away from you guys! We are getting soooo excited. This is our second cruise, only this time we are more excited, because we aren't taking the kid!
As for your wife, there are plenty of things to do, I am looking at one of our daily programs from our last cruise..there is a gym, exercise classes of all sorts, including yoga,walk a mile,pilates, etc...a spa, they have contests such as crosswords & puzzles, trivia, golf classes, weight loss challenges,ping pong tournaments, bridge/other card tournaments (not casino), wine tasting,art auctions, karaoke, scrapbooking classes, dancing classes,and tons of BINGO during the day, which on our last cruise my Husband and I loved....the pots are BIG if you win, at least bigger than any bingo I've ever been too, and that is just some of the stuff listed in one day...than at night, it gets really exciting..comedy shows, magic shows, dancing shows. Throughout every day and night they also have really funny shows like, "Battle of the sexes", Men's hairy chest contest", etc..
The "trick" to a cruise is I think to keep an open mind...go do stuff you wouldn't normally do, I don't know what it is, but carnival has a way to make EVERYTHING fun and hilarious...we laughed at all the employees in charge of the activities because they make everyone involved and keep everything sooo upbeat and fun! Take a few good books if you like to read...on our last cruise alot of people just sat down either in the sun, or in one of the cafes, or lounges and read. You can go swimming, eat, go dancing in one of many clubs at almost any time of the day!!
What is your wife planning on doing while your scuba diving in Cozumel??? We have been to Cozumel, and it is a really nice place to just get off the boat, and eat, shop, etc..but I know you mentioned she isn't into that. I hope this was of help...and I am crossing my fingers that both of you have a blast! Let me know if you have any other questions. Yeah only 11 days!!!!!!!
