Happened to visit singapore last week.. not happened.. planned and visited, my first tour overseas (personal). We planned for either singapore/srilanka/Andaman and zeroed in on Singapore and booked tickets in TigerAirways and the total cost of travel came around 10K (heard that it was a good deal) and booked beds in Frangrance hostel at Little india in Singapore, a night stay costed around 650 INR (22 SGD) and around 600 INR (20 SGD) for food and 250 INR (8 SGD) a day. In total 20K for 4 days of stay.
And except shoping centre and malls therez nothing much in Singapore. 3 days is good enough to spend and the sentosa island takes a day. A day for shopping and a day more to visit other places. Felt like roaming in the home place in Little India , guessed thatz y it got that name. Sentosa has good beaches to play, few rides and a Dolphin show (not to be missed). Night safari was not that impressive. And we could not manage to visit the zoo or the bird park. Shopping can be done in either China town or shops in and around Little india.
Over all, we had fun. http://picasaweb.google.co.in/shanmg/Singapore#
