My family is headed back to Japan end 2026 (a frequent destination for us) and this time we'd like to build on a 4-day stopover on the way in either Singapore or Hong Kong. We have never been to either place, although have transited through HK a few times (so we have at least seen the airport!)
Which of the two would you recommend? Our group will be 2 adults in their 50s, 3 adults in their 20s, and an older teenager, all with average physical fitness levels and no mobility problems.
