You can buy tickets at the Holiday Inn gift shop in Key Largo or go to the Key Largo Princess website. I also saw that the Groupon site offered an option for a discounted ticket. But, when I called the Key Largo Princess office to make sure they would accept the Groupon offer, they told me to just use their own discount code. We used it on two separate occasions by typing IHP in the discount area at checkout and it worked great. Both times we ended up getting tickets for less than $23/person.
