Hi, I'm planning a 5D4N trip to Medan for my family and intend to spend 2 nights on Samosir Island and 1 or 2 nights in Medan. Please advise which hotel I should be staying in Medan for easy walking to shopping and eating. What are the modern shopping malls around? And if my parents can't trek, is it still possible to arrange a trip to Berastagi? Is there any other activities for them? And do I need to trek too to see Sipiso - piso Waterfall?
