What are the key considerations for applying for a DTV Visa in Vientiane, Laos, with a child?

Hi everyone! I’m planning to apply for the DTV Visa via a House of taste Thai Cooking Class (Soft Power) in Vientiane, Laos at the end of March.

I’ll be traveling with my child (under 20) as a dependent. Since I’m currently in Phuket, I’d love some advice on the following:

1. Route from Phuket: What is the most efficient and cheapest way to get to Vientiane from Phuket with a child? Is the direct flight to Udon Thani + van to the border still the best recommended route?

2. Accommodation in Vientiane: Any recommendations for family-friendly hotels that are convenient for the Thai Embassy/Consulate? (Looking for places with good Wi-Fi and maybe a pool for the kid while we wait for the e-Visa).

3. Critical Documents for e-Visa: Besides the School’s Acceptance Letter and Syllabus, what are the "must-have" details that often get overlooked? For the 500k THB financial proof (from a Thai Bank), do I need a Bank Certificate or just the 3-month statement?

4. Applying for a Dependent (<20 y.o.): How does the process work for my child?

• Do I submit a separate application for him simultaneously?

• Is the Birth Certificate (English translation) the only proof of relationship needed?

• Can we share the same 500k THB bank balance proof?

5. Safety & Sightseeing: How safe is Vientiane for a parent traveling alone with a child? Any kid-friendly spots or hidden gems to visit during the 5-7 days waiting period?

Thanks in advance for your help! Any "do's and don'ts" for the Vientiane Consulate would be much appreciated.
