Well I was thinking of stoping there between Australia and Southeast Asia. I wouldn't stay very long as I wouldn't want to spend a ton of money, but would want to get a decent trip in the country. How long would you think is needed to see the city? What would you recommend seeing? How many left turns to get to the Indonesian Embassy?
Do you like shopping? Is it going to essentially be a free stop-over in Singapore? If the answer to both of those questions is "no", then I'd just skip it. There's really not a ton to do there, it's a banking city for wealthy people. I mean, if it's not going to cost you much money to stop over there, it's maybe worth it, but I wouldn't go out of my way to change my entire vacation schedule to accommodate it. You can do everything there is to do in the city in a weekend, tops. After the 2nd time I went, I ran out of things to do. Remember: it's tiny. Singapore is just a big city with a few KMs of palm forest, and then you cross the border into Malaysia. You can drive from one end to the other in an hour and a half.
Don't get me wrong, there's stuff to do there. Orchard Road is a shopping mecca for the uber-wealthy, and even if you're like me and can't afford to shop in a lot of those shops, it's still interesting to "people watch". Consider it
"Rodeo Drive: SE Asia Edition". I used to stay at a hotel on Orchard Rd. every time I went (because our company used to let us choose our hotel, we didn't pay), and it was fun, but not so fun that you absolutely need to fly there specifically to see it. It's just nice restaurants and expensive clothes. No big deal.
Other than Orchard Rd,
1) the Raffles Hotel is a historical landmark, and worth seeing if you're already there (but clearly not worth flying into the city specifically to see).
2) The Gardens By The Bay & Cloud Forest (they're next to eachother) are probably my favorite thing there, but you have to be into nature and architecture to get anything out of it. If you are, it's a must-see. If not, you will be bored to tears.
3) The Singapore Zoo has a very cool "Night Zoo" attraction (go at night to see nocturnal animals), which was neat but also hilarious. We went to see a show where they paraded around exotic nocturnal animals for the crowd, and the grand finale was a raccoon. Like
"WTF, I have seen those trash pandas my whole life, this is not exotic, let alone exciting enough to be the finale", but then you remember that raccoons are not native to Singapore or most of SE Asia, so it's cool for them, I guess.
4) Marina Bay Sands is a total letdown in every possible metric you could use to evaluate letdowns. Do not go. It's full of disgustingly wealthy businessmen with the manners of a stray cat, and you can't even go swimming on the rooftop pool unless you are staying at the hotel, which is massively overpriced for what you actually get.
5) Singapore Flyer is... meh. It's a cool view, but it's like $30/ticket or something crazy, and a 15 min ride, and entirely dependent on it being a clear day to get the best views, and it's almost never a clear day in Singapore.
If you're into auto racing, they have an F1 race there every year, too. Dates change every year, but it's usually in September at some point (and I was always in Singapore in August every year, and again in Oct-Nov, so I always missed it) I dunno, maybe you can time your trip up with the race?
So yeah. Cool city, but not special in any way, unless you want to open a bank account... which, as someone who still banks in Singapore, I can personally attest to it being the best banking experience you will ever have, bar none, with no exceptions. Also: taxis are assembly-line-level efficient there. You'll see when you get there.
On a related note the company I will use for my SE Asia tours put up their August deals today. One of them happens to be that if you buy the Thailand-Laos-Cambodia-Vietnam tour you get the Myanmar one free! That saves me about 1000 USD! I think I will use that money and spend a week or two in South Korea before flying home.
Well, now there are no excuses, you have to go.
