Elch,
Would recommend Club Med. Though is at the higher range, but everything is inclusive! Meals, activities (land & water sports) & kids club..
If yr child is above 4 yrs, u can leave him or her at the Mini club where they will a full day activities of fun! U & hubby's can relax at their private beach without yr kid.. Er ren shi jie! But if 2-3 yrs, u can enrol for petit club at an expense lah..
