Island hopping — which islands actually worth?

Half day hop hits 3–4 stops max despite "8 island" marketing — Pulau Dayang Bunting lake swim main event, sandbar photo stop, snorkeling meh. RM80–120 from Cenang jetty. Skip if doing Kilim same trip day — boat fatigue. Private speedboat RM400 split if hate crowds. Morning departure less chop. Life jacket for kids.
