Hello! I'd be happy to assist you with your travel plans to Kuala Lumpur.
For your accommodation, there are many great options available depending on your budget and preferred location. Some popular areas to stay in Kuala Lumpur include Bukit Bintang, KLCC, and Bangsar. You may want to consider booking a serviced apartment, which will provide more space for your family and amenities like a kitchen and laundry facilities.
One option you might want to check out is the Ascott Kuala Lumpur. It is located in the heart of KL's Golden Triangle and offers luxurious apartments with access to a gym, swimming pool, and tennis court. It also has a car park available for guests.
Genting Highlands is located about an hour's drive from Kuala Lumpur and is a popular destination for families. It features an indoor theme park, outdoor activities like ziplining and abseiling, and a casino. You may want to consider staying overnight at one of the resorts in Genting Highlands to make the most of your visit.
As for my own travel experiences in Kuala Lumpur, I highly recommend checking out the Petronas Twin Towers, visiting the Batu Caves, and trying out the local cuisine at street markets like Jalan Alor. Enjoy your trip!
