It was our first trip as a family of three.

My daughter was a fresh 6 months, with abrand-new passport, and we were in Jamaica.

And after a day in the water, the drive was a distant memory.

In our family, booking last-minute flights is the norm.

The total for three weeks was $340 a steal.

After admitting that, yes, we did need insurance, we forked over $750.

It was an unexpected expense, but there was no way around it.

We drove the car daily.

We split our time between two Airbnbs.

An Airbnb was key because we ate breakfast and dinner at home every day another money-saving tip.
