Travel Gurus - All Inclusive Caribbean Resorts

I know these threads pop up a lot, but I am going to surprise the wife with a trip to the Caribbean for our anniversary. It's Tuesday, so rates may be a little lower. Was looking for legit all inclusive places in the Caribbean, looking to stay 4 or 5 nights and would like to keep it in the $450 to $600 or so a night range. We aren't really looking for activities or anything, just relaxation and nice beaches and as few guidos as possible. I appreciate your recommendations.
