Switching to a cheap gas supplier could help boost household coffers, allowing a family to head off on a cruise.
Cruises are not as expensive as many people assume, asserted Cruise Critic.
Many of the onboard activities - like bowling alleys, climbing walls and kids' programmes - are free, with all-inclusive options often meaning parents hardly have to splash out.
Reducing household expenditure through cheap gas bills may mean families can afford to treat themselves to a holiday at sea.
"Cruises are so popular with families because of the flexibility they offer; you can spend as much or as little time together as you like, with kids clubs even open on port day," managing editor of Cruise Critic Melissa Paloti stated.
According to the Passenger Shipping Association, 75,000 children in the UK will go on a cruise this year.
This is seven times the figure seen ten years ago, which may show how travelling by boat is increasingly popular.
