Is there a Potty Training camp?

Why is it so hard to potty train twins? Can’t I just send them off to a potty training camp somewhere? I put the twins in underwear this morning and they have had accident after accident with no successess. I put them on the potty only to have the pee in the pants ten minutes later. It is so frustrating!!! I don’t think they are ever going to get the hang of this.
