As a 103/104 instructor, I'd say no to the kids unless you're getting a private lesson (you and the family are the only people aboard other than the instructor) due to the possible impact on other students on board. We would also have a clear and frank discussion about safety and time/attention paid to the course material, both learning and practicing, vs. taking care of 5 and 7 yo boys, especially if they have issues

having had two sons, I think I can speak from experience.
These two courses cover a lot of material and 5 days is a minimum, 6 or 7 days preferred, not a weekend...
