Food, yes. Swimming, use of the water slides, beach, games, etc. is all included. There is no charge for snorkelling, but there is an equipment rental fee. We had our own equipment, so we were ok there. You can also rent bikes, water floats, etc. And there are wave runner tours, stingray encounters, etc, which all cost.
But don't assume away the other differences people tell you about. In almost all areas, DCL is better. The question is whether it's enough better.
