I'll be going with my 9 year old son to Vietnam in March. There are cheap flights to HKG, and a cheap flight from HKG to Ho Chi MInh City, but the connections don't work.
Would it be worth it to spend a night in HKG on the way there and back? Are there any cheap but clean places to stay with a 9 year old? Are there things of interest to see for children?
Would we need a visa for HKG, and would that even work if it's 1 night on each leg of our journey?
