Is it worth switching to a fridge with vacation mode or is it just a waste of money?

The holiday mode is actually a really useful feature if you throw big dinner parties or cook a lot of food at once. It lowers the temperature more than usual and keeps it stable when you're constantly opening the door and warm air is getting in. If you live alone or with one other person and rarely cook for large groups, there's no point paying extra for this function.

Financially, it all depends on your situation. A fridge with holiday mode usually costs more, but the difference isn't astronomical - it's mostly in the price of the fridge itself. That said, if you actually use it regularly, you can save a noticeable amount on food that would otherwise go bad. But if it's a mode you'll turn on twice a year, it's not going to pay for itself.

My advice: think about your habits. If big grocery hauls and cooking are your normal routine, get a fridge with this function. But if you usually cook for two or three people and you're fine with that, you can go with a more budget-friendly model without the mode. There are so many models out there these days that you'll find a good fridge at any price point.

It all depends on your habits - if you're actually frequently loading up the fridge with a bunch of groceries at once or often opening the door when you have guests over, then the mode makes sense. If your fridge is running in a calm mode most of the year, then there's no point in overpaying.
