Help me choose: Sugar Beach, Cap Cana, Nevis, Grenada??

Looking to book a summer trip with wife and kid (2 years old). We loved Sugar Beach Viceroy and are thinking of returning but also have that feeling of wanting to go somewhere new. Should we go back to Sugar Beach or look at something like Eden Roc Cap Cana or Silversands Grenada, Four Seasons Nevis?

Things we look for: – Good beach – Villa style (so kid can sleep in separate living room) – fun resort / activities / fun bar at night – experiences you can do outside the resort – kid friendly

Thx!
