Plenty of travelers cruise to see as much of the world as possible, but that doesn't mean you have to scramble ashore in every single destination in order to feel like you're getting the most from your vacation.

Sometimes staying onboard while in port can help you to reset and recharge, particularly if you're sailing on a port-intensive voyage. It also means you can avoid the early-morning rush of people jostling to be the first to disembark.

On a limited budget but still hoping to snag a few mementos from your vacation on the high seas?

Check out our list of 10 cruise souvenirs you can find onboard most ships for the low, low price of absolutely nothing at all.

I love cruises, and there is definitely one for everyone, but there are certain kinds of cruises that are simply a bad fit for good reason.

Whether it is high expectations not meeting reality, or highly specialized sailings that do not mesh well with newer cruisers, I have a breakdown of the top cruises to avoid and why.

Although it will likely be a long time before cruising returns to normal, several sailings have resumed for American passengers; now, more than ever, they are left wondering whether it's necessary to purchase cruise travel insurance.
