Steve,
I second the opinion that taking the kids would be wonderful, a lot of people here has said that taking a nanny would be a good solution.
My wife almost started working as a tutor/nanny for
tutors, tutor recruitment, private tutors & private tutoring – tutors international. In my opinion a great, but expensive, way for finding an experienced person that will help with your kids while making sure that they don't miss out on any schooling they would have gotten if they stayed at home.
Also...Kid Kennel... ugh don't think that that will ring very well with most parents , you wouldn't want to treat your kid like an animal.
ps: if you go the tutorsinternational route, I wouldn't mind a ping to get a referral
Aloha,
Hugo
