I left Thailand in 2001 expecting to return in a year. Unfortunately, that didn't happen and I didn't use the account again until 2005. Updated my passbook in 2005 and noticed I had around 1,500 baht in it which was more than I thought would be in it. Old ATM debit card had expired but I got a new one. Everything went very smoothly. This was years ago so maybe some of the banking rules have changed.
I became a lifetime member of the Pattaya Expats Club back in 2006. I have rarely attended any of their meetings since then. I just haven't felt the need or desire to attend.
"Passengers took pictures onboard as the drama unfolded." Why? Were they going to update their status on Facebook, Instagram, or some other social media platform?
The way that condos are run and the quality of them I would be very wary of actually purchasing one. There are definitely more condos for sale in the greater Pattaya area than there are buyers. There are so many things that you can't control such as neighbors plus Air BnB's, but then the condo management is a whole other problem.
Good luck in your search.
People cross the Thai/Lao border all the time with bicycles. It's no problem at all. Lots of people cycle from Vietnam to Laos and then on to Thailand at various border points including the one you intend to use.
I have avoided flying Thai Airways internationally for many years. It's pretty easy as they don't serve the city I live in at my home country. I would have to fly somewhere else first and make another connection. There are many other Asian carriers that serve the city near me so I just fly with them. Plus the other carriers are all significantly cheaper to fly with.
I think a 90 day visa free program would be very good for a lot of people whether they stay 45, 60, or the full 90 days. If they can easily extend for an additional 30 days that might be even more attractive. A lot of older people want to escape the northern hemisphere winter and this might suit them well. It's definitely better than what they are currently doing.
According to a few different Thai legal providers having a lawyer present is one of your rights. Here is one such source.

I think Thailand’s Deputy Prime Minister and Foreign Minister Parnpree Bahiddha-Nukara will soon be walking back some of the comments he made when the tourism goals for China fall very short of their targeted numbers.
So many possible outcomes to this scenario. The new Swiss husband, the sister, other relatives, even the abbot of the nearby Wat could all be possible suspects. Or maybe she just ran off with the money to start a new life somewhere else.
