It seems like a win-win -- invite your child's best friend to join you on vacation so he or she has a built-in playmate. But before you offer, consider the pros and cons.
Choose the right friend - usually a well-behaved kid who shares your child's temperament and interests
How well do you know the friend's parents?
Do you share parenting styles and values?
How will you discipline?
Consider the costs - Are you able to pay for an extra person, larger lodging, food, attractions, shopping, and snacks.
Plan for minor health issues
Be prepared for emergencies
Have boarder paperwork if necessary
The best guests to bring along are kids you know well and have a long-standing friendship with your child. Start with a short trip and see how it goes. Are the kids able to stay on their best behavior in front of their company?
