Some of my friends living overseas visit Singapore for few weeks while their kids go to summer / holiday camps. Wanted to share some info that I got and experienced:

Camp Asia

• Good programmes (sports activities, arts, drama, coding, cooking etc) and decent number of staffs, which is good
• At Stamford American International School (SAIS) with good facility OR held at Australian International School, depending on period, but SAIS recommended
• Provides morning snacks, lunch and afternoon snacks. Heard the quality is quite good!
• Provides shuttle (my friends stayed at hotels at Orchard and it was very convenient for them, and River valley area works I heard). Highly recommend to check if the school bus comes to your place before singing up…
• Used to be from 8am to 3pm but not sure if this is outdated.
• Price: SGD 600 - 850 depending on the days (4 / 5 days) and programme that you sign up.

• Select the programme by age and by week
• Programmes include art, musical, language, sports, coding etc
• 9am - 3pm, five days a week (some are 4 days)
• Two location options: Tanjong Katong and Lakeside. Lakeside campus is bigger than one in Tanjong Katong, so there are more programmes available.
• Price ranges from SGD 560 - 700 per period per programme
• Includes morning snack and lunch
• Availability here: http://online.cis.edu.sg/Holiday-Program-Camps/
• When you sign up for early bird they used to provide 10% discount, but no refund I recall.

Newton show

• Located at Newton / Novena (one at Goldhill shopping mall and another one at Goldhill plaza) and I think they expanded to few more. Smaller scale then above.
• Multi camp programme has different topics like cooking, art, robotics, science each day.
• Summer camp programme has multiple options like: space explorer, unbelievable science, Harry Potter science, lab etc. So very science focused. They bring some science products they make.
• I heard birthday party programme is quite popular too
• Price: 685 SGD
• 9am - 4pm, Mon - Fri per week
• Door to door transportation when you register
• Provides lunch and two snacks.

• Mindful Robotics: 6 hrs workshop and 1 hours lunch (bring own lunch). Priced at SGD 290 per child
