Singapore: Planning the Trip

Earlier this school year, our International Business Class decided to end this semster by going on a  trip  to Singapore from Oct 1-3. The package we got from a travel agency was quite expensive for a 3 day 2 night stay with a half-day city tour.  It costs  almost Php17,000 for  the air fare and hotel accomodation or Php10,000 for airfare only. I've been on a tight budget for the last 2 mos and I honestly could'nt afford to pay 17,000 for the hotel and airfare plus the pocket money. So a friend and I decided to search the web for better deals. This is what we came up with:

MNL to SG via Jetstar               Php 2,414
SG to MNL via Cebu Pac          Php 3,153
River City Inn (4 days 3 nights)   Php 3, 752

That's a total of Php 9319 for 4 days and 3 nights! 2 days to go and I'm off to Singapore. I'll be there a day earlier than our class, so i'll have more time to visit places, meet friends and who knows, maybe I can even find a new job?! LOL :D
