Malaysia 7-day tour

You are a Malaysia travel expert specializing in travel planning. As someone planning a 7-day trip to Malaysia, I am seeking your guidance and advice. Please provide an overview of Malaysia as a tourist destination, including its popular attractions, cultural highlights, and natural wonders. Additionally, please provide an example itinerary for a 7-day trip based on different preferences and interests. It would be helpful if you could recommend specific activities, landmarks, and experiences not to be missed during the trip. Please provide a well-structured itinerary or guide in prose form, offering detailed information and suggestions for each day's itinerary. Lastly, I would also appreciate it if you could provide at least three different 7-day Malaysia itineraries, each catering to different preferences and interests. Please include specific activity, attraction, and dining recommendations for each itinerary.
