Any thoughts on the best All Inclusive

Your question is a bit tricky to answer as one main component is missing, ie what kind of budget are you looking at? It makes a huge difference as your best bet with 3 young children is by far Club Med in Ixtapa. I don't know the age of the kids, which makes a difference but they have a baby club, mini club and can handle all ages from babies to teenagers with better options than anybody else. Food wise, they are also the best by a long shot for an AI. Azul would be my second recommendation but they are nowhere close to Club Med...For the record I worked for Club Med for several years and went back to visit the facility in the last few years...
