2 week Vietnam Itinerary critique/ advice

I’m planning a solo travel Vietnam trip and I’ve tried to build an itinerary that focuses on nature + culture + history + meaningful experiences (not just tourist checklist stuff).

Current plan:

- Hanoi (2 days, including Hoa Lo Prison)

- Ha Giang Loop (3–4 days)

- Ninh Binh (2 days)

- Fly to Central Vietnam → Hue (2 days) + Hoi An (3 days)

- Ho Chi Minh City (2–3 days for war history — War Remnants Museum + Cu Chi Tunnels)

A few honest questions:

1. Bay question (very confused):

Is it actually worth adding Ha Long Bay / Lan Ha Bay if I’m already doing Ha Giang? I’m not into swimming and I’m worried it might feel slow / touristy. Should I skip completely, do 1 night (Lan Ha?), or is it a must regardless?

1. Sapa vs Ha Giang:

   I’m currently planning Ha Giang, is there ANY reason to also include Sapa? Heard it has become touristy now.

2. Pacing:

Does this plan feel too rushed or actually well-balanced?

1. War history:

   Are the War Remnants Museum + Cu Chi enough, or is there anything else truly worth adding for history?

2. Anything I’m missing that is genuinely special (not just popular)? I have the possibility to extend the trip for few days.

Would really appreciate advices. I am so excited for this trip 🥹🥹
