I believe the site is
www.jamaicavillavacation.com . I haven't stayed there, but heard it was a pretty good deal. I think he has a few places to stay at.
I have stayed in a few all inclusives in Jamaica. I heard the FDR Pebbles was a good place for kids. I think they provide a nanny for the kids. I heard it wasn't ultra deluxe, but the childcare makes up for it for alot of people. I have never stayed there so I can't tell you for sure.
Alot of these folks have interline rates, call them direct or use a interline travel agency like perx.
