As that great philosopher the Cat in the Hat once said, it's fun to have fun but you have to know how.
It's a belief which has been taken on board, literally, by Carnival Legend crew with the mischievous hat-wearing feline, Sam I Am, Thing One, Thing Two and other Dr Seuss favourites joining young passengers for some cruising fun.
Suess at Sea is just one of the initiatives which aim to keep the kids entertained on Carnival cruise ships so the parents can focus on the important task of relaxing.
"We carry more families than any other cruise line in the world and we're always trying to expand our horizons when it comes to ensuring kids, and their parents, have a memorable and enriching onboard experience – and a great holiday," Carnival Cruise Lines Vice President Australia and New Zealand Jennifer Vandekreeke says.
My family was fortunate enough to spend two hours onboard the Carnival Legend while it was in dock in Sydney recently, giving my two young sons the chance to road test the ship's kid friendly activities.
First stop was a Green Eggs and Ham breakfast. From all reports the colourful dish was delicious, but my boys chose the Truffula Tree Pancakes which they declared were "awesome".
During the special breakfast, which is held on each Carnival Legend cruise, the Cat in the Hat and Sam I Am wandered around greeting young diners with high-fives and hugs at their tables.
The fun-loving characters, Cat in the Hat table decorations and a cast of dancing waiters dressed as Thing One and Thing Two combined to make the experience a special one for my young Dr Seuss fans.
Next we were off to the ship's theatre to watch Hasbro, The Game Show where a host lead the young audience through an entertaining game of giant Connect 4.
The full-length show held during cruises also gives families and friends the chance to team up for the games Sorry!, Sliders, Operation Sam Dunk and Simon Flash.
But now it was time for us to head up on deck to Carnival WaterWorks and for the truth to be revealed - who would be tall enough to ride the famous Green Thunder and who would have to wait until next time?
Green Thunder is a steep, free-falling slide which reaches speeds 65 kilometres per hour with riders required to be at least 122cms to ride.
To my surprise, and slight horror, my lanky six-year-old easily reached the height marker and excitedly ran up the stairs to take his place in the line of brave sliders.
"That was great! I'm going again!" was the enthusiastic response I got as my boy shot out the end of the slide.
Those who are not tall, or brave, enough to ride the Green Thunder don't have to miss out on the fun, with the Twister waterslide offering a much tamer experience.
Meanwhile my almost three-year-old happily splashed about and kept himself entertained in water play area while his daring big brother rode the slides to his heart's content.
In addition to the activities my very willing cruise ship testers took part in during their time onboard, Carnival boats also feature pools, spas, mini-golf and plenty of other games and activities to keep the youngest family members happy.
The cruise line last month announced the kids club on board the Carnival Spirit will undergo a refurbishment this year before being unveiled as Camp Ocean.
Camp Ocean will be designed for children aged 2 to 11 and will offer more than 200 ocean-themed activities such as sea salt art, sea shell craft, ocean bingo, and make-your-own sail boats.
"We can't wait to introduce Camp Ocean to our Australian ship and watch our youngest cruisers dive in to the wonderful world under the sea," Ms Vandekreeke said.
Carnival Spirit's current teen programs will remain to entertaining guests aged 12 to 17.
So it seems all that is left for mum and dad to do is locate an empty hammock in the Serenity Adults Only Retreat and wait for a waiter to take their cocktail orders.
