What details should I include in my Thailand DTV application regarding arrival, departure, and accommodation plans?

(UK) Travel information question on the DTV application for soft power

For intended date of arrival, I have a flight booked from the UK on 7th April, stopping in China for 1hr 40 mins, and I land In Bangkok on the 8th April

So I will write intended date of arrival as 8th of April on my application.

For intended date of departure- I don’t have a outbound flight booked yet. I was going to

Book that once I had confirmation of the DTV or not (I’ll still take the flight regardless of the outcome)

So I was going to write intended date of departure 24th September 2026 (170 days) ?

For the last port of embarkation - I should choose China, correct? As I stop there to change flight for Thailand.

I need to pull up my flight info for my flight number.

Lastly - accommodation in Thailand

How much detail did you all give for this? I haven’t booked anywhere to stay yet. Could

I write the address of a place I MIGHT stay at, for the applications sake? And maybe just write duration of stay ~ 7 days or 10 days or something?

My girlfriend is Thai and she has a condo in Bangkok so should I also include this on the accommodation and duration of stay ? As I would also stay with her - or is there no need, and I don’t need to give this much information, unless they request it
