Cruises may be pricey-- but if you love the theater, you may be in for the deal of a lifetime.

Most lines now offer Broadway or Vegas-caliber shows year round. Welcome to the new world of onboard entertainment as cruise lines up the ante with more hi-tech theaters on new ships, and elaborate productions crafted by Broadway veterans, top-tier choreographers, performers, and lighting, staging and scenic designers.

“We’ve seen a truly exciting evolution in onboard entertainment, offering cruisers just as incredible an experience at sea as they’ve come to expect on land," Colleen McDaniel, managing editor of Cruise Critic told FoxNews.com. 

Princess Cruises has just announced its second musical production show created in collaboration with Oscar, Tony and Grammy-winning composer Stephen Schwartz. “Born to Dance” pays homage to Broadway choreography and dancers and will debut on the Star Princess this fall. 

Younger fans can join the new “Day of Frozen Fun,” aboard Disney Magic and Wonder sailings to Europe and Alaska this summer, complete with a “Freezing the Night Away with Anna, Elsa and Friends,” song-and-dance deck party.

McDaniel notes the biggest trend right now is the use of the latest technology to enhance entertainment venues.

“Whether it’s IMAX at sea--exclusively on Carnival’s new Vista-- or giant screens to bring an entirely new dynamic to traditional shows, cruisers have a lot to be excited about when it comes to new entertainment options at sea."
