When packing for a chalet stay in Singapore, you should always start with the basics. Bring comfortable clothing suitable for the climate, such as breathable t-shirts and shorts. Don't forget to bring a few layers as the nights can be cool. Include a raincoat and rubber sandals as you might find yourself needing them. Be sure to bring along toiletries and sunscreen as well. Don't forget to also include entertainment such as books, board games, and cards. Lastly, bring a bath towel and some snacks to munch on!
