Two of us on this trip are married, one with young kids. In this case the kids are with grannie and have a list of chores / Skype on their computers.

Sometimes team members take vacation at or close to the location with significant others after the work trip.

We talk about these trips when describing the company as part of our interview process. It wouldn't be a problem if people were unable to participate because of their personal situation - we're well used to working remotely. Almost everyone sees it as a big benefit.
