How about if you allow your kids to go play for limited periods of time, so that you know that the other parent isn't being overwhelmed? Maybe for an hour, for instance. Set a time limit to return home and if they haven't then call the other house or drop over to retrieve them. That would give you the chance to touch base with the other parents as well and get feedback on whether your childrens visits are intrusive or not.
I'll bet most parents don't mind short visits when they know the other parent is keeping tabs. Likely it's the kids who seem to hang out all day with no supervision who are the problems.
