Which should I choose? Bali-Manila or Bali-Singapore-Hanoi

Hi guys! Can you help me decide + share your cost/experience for my planned trips?

My planned trips:

July 25-July 30 - Bali with family

July 30 - They'll be going home to Manila

I was supposed to go straight to Hanoi with my sister to meet with friends but her friend cancelled so she's going to Manila with my family. My friend already booked her ticket so I'm still going to Hanoi. The problem is, she'll be arriving on August 2. Thus:

My two options:

  1. I'm going home to Manila to rest and repack, then I will fly to Hanoi on August 1
  2. I will fly from Bali to Hanoi, through Scoot. So other than it being the cheapest flight + there's a Singapore layover too. (Singapore in July 30-31, Hanoi in July 31-August 1)

My situation:

- I am not a solo traveller, and this will be my very first solo travel (Singapore-Hanoi for a few days). I am a bit wary but also, I know I can hold my own (23, female, I look like a victim, but I can hold my own in the countries mentioned, they're very safe).

- I want to choose whichever is cheapest + worth it

- If Option 1 is significantly cheaper (Bali-Manila-Hanoi) (by around USD 80-100), I'll choose Option 1

- If Option 2 is significantly cheaper, or only slightly more expensive than Option 1, then I will choose this for the experience. Again, USD 80-100 is the cost difference I can tolerate

I attached the image of the cost comparison, based on the current price of flights right now (+ image attached).

I'm still not entirely sure of the realistic cost of the Speeing Pod, Food, and Activities in Singapore for a layover flight, and Acommodation and Food in Hanoi. I am researching it inmy spare time, but I also want to hear your suggestions!

What I need help with:

  1. Can you share your experience/cost in either or both Singapore and Hanoi?
  2. If you can weigh in on what is the better option based on experience in the same flight/destinations, I would love to hear your thoughts!
  3. What was your experience solo travelling?

I am the type of traveler that most hate. I love photography, so I take photos a lot, it is the highlight of my trip for me because I can enjoy it after the trip pa hehe. I love wearing cute clothes, but I am willing to bring less/maneuver the luggage situation, so I only bring 7kg for Option 2. I want to stay longer in one place to appreciate it and explore every nook and cranny than going everywhere. I am less of a traveler and more of a vacationer, so I might not enjoy Singapore if I'm exhausted but it's Singapore, so I think I'll enjoy even if I stay in the airport and only leave for the city center for dinner.

Please be kind, even if you don't agree with my travelling style. I just wanted to hear the thoughts of veteran travellers/those who have done the same trip as the one I'm planning. Thank you.

If I missed any details, please ask. I will kindly provide more context, I just think my post is already too long.
