I am going to pick Africa as many have not been to that part of the world. I suspect that Singaporeans who have visited Africa tend to go to the Pyramids in Egypt or to South Africa. I have been to 11 countries in Africa and the most consistent theme i found is that English that is spoken and written properly is common place. Street vendors in Nairobi, Harare etc converse in proper gramatical English. Their vocabulary is also lot more extensive than I thought. Only Egypt's standard of English was poor.
Ldanguage wise the most bizarre country was Mauritius. Lingua franca is french creole. Official language of court, parliament, road signs are in English as well as it is the language of school instruction. But most popular newspapers are in proper French. It is also the practice to send their kids to Sunday school to learn their own mother tongue which may be Hindi, Chinese etc. so they can effectively speak 4 languages fluently. The study of mother tongue on Sundays is pretty stick evem though it is private matter.
It is not surprising that Africa is often missed out. Besides South Africa and Egypt, many countries in that continent are "less developed", in conflicts or civil war at one time or another.
I suspect that many Singaporeans had visit Morocco. where the northern region feels like Malaysia and the southern feels like Arabian nights.

Libya was alright under the late Qaddafi. A Malaysian work destination.
Namibia, Botswana, Kenya, Nigeria (city is unsafe now) are safari destinations.
Victoria Falls and Mt Kilimanjaro should be familiar.
Many people like Egypt but I will pick Morocco mainly
because at first look, there is nothing to offer seasoned tourist like me (eg do you still want to visit another Roman ruins). But visit the place and live in one of the Imperial cities for a while and you will learn to love the place and the local people, and you do not wish to leave. This is one place where tradesmen cannot afford tools to carry out the riad's renovation but the people are still practical and they do not attempt to cheat you.
Other than Marrakesh, the taxi drivers do not cheat, but I have difficulties getting into one of those
petite taxis (Fiat Umo). But we can get a chauffeur with a Dacia (Renault) car.
It will be a nice change for Singaporeans.
Whether is it the Andalusian (Spain) influence in Fez ancient narrow-lane city which we can find in old part of Europe, like Lisbon, Portugal.
We can live like kings in the renovated houses that are for rent. It is a lovely experience where you can get close to the people.
For people who live on US$2 a day, it is a refreshing change from the decadence lifestyle of how we live. I wonder how long this decadence era will last, the decline is already evident but politicians heads are still stuck in the sand.

I did not know that there are Cantonese food in Mauritius until I met people from that island.
