Thank your favorite teacher for all they do by helping them win a cruise!

Norwegian Cruise Line is treating 15 lucky teachers to a cruise in honor of Norwegian Joy's upcoming debut in North America, a cruise line spokesperson explained.

Anyone can nominate a teacher, and teachers can even nominate themselves.

"Nominate an educator who demonstrates a passion for spreading the joy of learning (or, if you are one, nominate yourself!)," a spokesperson said.

All you have to do is explain what your nominee does to bring joy to the classroom, and then, you just have to vote.

The top 15 teachers will win a free cruise for two and an invitation to a special award ceremony on May 3 in Seattle. Norwegian said they will take care of airfare and accommodations. One lucky grand prize winner will win $15,000 for their school.

The contest ends on Friday, April 12.
