In general I’m not a fan of privates.
Scheduled group training should be enough to meet the individual goals.
But I have to admit — privates work. When parents & kids are motivated to add an expensive additional lesson to the regular training week, they often succeed.
Chalk Bucket has a thread on the pros and cons of privates.
An alternative is to offer an additional workout for ALL gymnasts in a given group. Those who want extra can sign-up as desired.
