if u only have 2 days to do diving.. there are many option.
1) local liveaboard - boat leaves from singapore.
they usually go out from a friday night.. and comes back to singapore by sunday night.
they usually go to 2 place... tioman island (malaysia) or Anambas Reefs & Pinnacles (indonesia). I prefer anambas vs tioman.
These are the boats to contact in no particular order:
Diving Singapore | LOB Singapore | Nautica Diving | MV Nautica
GS-Diving | PADI Scuba Diving Courses in Singapore
DiveRACE | Scuba Diving | Padi Diving Course | Diving Equipment | Learn to dive | Trip Booking

2) dive local
- singapore has the smallest marine park in the world.

slots and timing are limited.
- hantu ( if you love low vis and like to take pictures of macro)
http://www.pulauhantu.sg/dive-with-us/ or search "SG Underwater Macro Photographers" in facebook
a great and unpredictable place to dive, mostly can be 1m or less visibility, but they are many small critters.
3) travel out
1 )sipadan - need 1 day to get there at least.
2) manado/lembeh - not daily flight out from singapore and back
3) tioman island - by land you can also get there, but i will not recommand do it. you set off friday evening around 6-7pm. they you travel through the sg and malaysia customs through the night to the ferry point in malaysia. arrive at the ferry point at around midnight or later. then take the ferry to tioman island. arrive probably early in the saturday morning or by 7am. then off you go diving till sunday tired yet? then you dive 3-4 dives on saturday and sunday you do 2 dives. then you make the whole journey back in reverse. tired yet?
you can also book yourself with dive centre on tioman island yourself. its a nice place to relax anyway.. B&J tioman diving , Ray diving tioman. are some you can choose to dive with.
4) bintan - 45min ferry ride from singapore
cost of ferry tix is around 70-90SGD. 45min ferry.
you can look for tasik ria bintan. they can arrange everything for you from ferry, diving, stay, etc.
its mainly macro here .. vis will be the same as in singapore, but maybe slightly better.
hope you find something...
