Hi Hive account@akilie1029! Our plane ticket costs 5K/person roundtrip with 25kilos check in baggage SNG-MNL.
We bought attaraction tickets here in PH using the klook app. Maybe we bought it for 6-7K (sentosa adventure, USS, GBB.) It was very helpful plus it has discount, i totally recommend this to you. Our pocket money was around 15-20kphp. We have a friend who lives there so it was a big help for us that we had a place to stay. Our overnight stay in MBS costs 500+SGD. So maybe you have calculated our budget during our trip. I'll tell you, it was not a friendly budget. 😅
