What You'll Pay: Cruise travelers are often lured into dropping big bucks at the onboard photo gallery, where an 8x10 photo can easily cost $20 or more. Buying additional batteries, memory cards and other camera supplies onboard will likely cost you more money than it would back home.

Savings Tip: If you're worried about blowing your budget on photos, just say "no thanks" when the ship's photographer asks to take your picture. Or resist the urge to "just check out" the photo in the gallery -- once you see the printed version, you're more likely to want it. Take your own pictures, and rely sparingly, if at all, on the ship's photographers. If you do plan on buying a lot of professional photos, look for packages or ask about any specials on offer.

On the equipment side, buy plenty of batteries and other camera supplies at home where they're cheaper -- and bring more than you think you will need, just in case. #inCruises
