1. Don’t arrive at lunchtime between noon and 1pm. It’s totally shut for lunch.
2. Print all copies beforehand. The copy and photograph shop is closed all day Saturday
3. Tried beforehand registering the TM 30 online on section 38 app for Android, IPhone and web. None worked.
4. Google maps is out of date on finding the location as there is construction nearby. Probably best to take a taxi rather than driving yourself.
TLDR : Answer Summary
When registering for TM 30 in Muang Thong Thani, avoid arriving during lunchtime (noon to 1 pm) as the office is closed.
