B.S.
I just moved here to Schofield Barracks a month ago so there are a lot of things I could answer if you want to pick my brain. I'll also send you a private message so you can contact me more directly if you'd like.
If you choose to live on base the Enlisted housing is superior to anything you'll find off post for the same amount of money and chances are you'll end up with a lot more room too. I have a 4 bedroom house whereas most comparable places off post we only 2 bedrooms or very small 3 bedrooms.
They have a preschool library time once a week for ages 0-5 and you can meet a lot of other mothers there. I have a playgroup I attend with my 2 year old son and the ladies are really nice.
When I first moved here I had no idea about anything because we only had a week from the time we found out we were coming until we actually had things in motion to come. I'd be happy to help you answer any other questions.
