A family of three is going to road trip, and friends want to go. Should I take them?

We shouldn't bring friends. We need to know each other's ideas about money, so as to ensure that we have similar ideas about money on the trip. Many people will choose AA system when they spend on go on road trip, but partners who have a strong concept of money are more haggle over every ounce, which will be very clear and sometimes make us very unhappy. Others like to take advantage of small things. They pretend not to hear when they check out, and they often find fault with each other on the trip, because they complain to everyone about a little thing, complaining about their poor food and lack of warmth.
