As I stated...continue with your plan.
I have pointed out the changes to border crossings. I'm very aware of flying DMK to UT return. Then run to Nong Khai.
In addition you're coming from Rayong not Bangkok.
Enough.
You haven't even read this thread.
Here is copy from earlier post.
Things have changed in regards to border bounces.
Even previously safe easy crossings such as Nong Khai have changed.
Of course the agent minivan runs are safe.
Did you read link to thread I posted earlier. Guess not.
Continue with your plan.
Things have changed at Nong Khai.
Without agent plan for 2 night stay and even asked for flight to home country.
However have not read recent reports.
Yet you go to Nong Khai?
Here is thread covers agent runs to Cambodia from Pattaya.
You should be able to do it same day.

Same Same.
This is all news to you having stayed in Thailand so often.
So to be clear ....are you located in Rayong?
That makes little sense to go to Nong Khai
Is that a typo.
If located Rayong you would do border bounce using one of the agent companies located Pattaya.
They run to Cambodia. No issue.
BTW: The idea of exit and reenter via air same day is crazy given your history.
Non O based on marriage to a Thai has nothing to do with your situation.
What you are asking about is non Thai wife piggyback on your Extensions from a Non O based on retirement.
If e-Visa provides option for her to obtain Non O as a dependent then that's a possibility.
She needs to obtain the Non O outside of Thailand.
Put child aside for the moment.
I read your other threads. Are you now on birth certificate?
Have you considered DTV .
That provides for non Thai spouse.
This blog guy gives good explanation.

If you are asking this in relation to border bounce then suggest minivan agent company best option.
Go to your bank and discuss "credit advice"
Kasikorn also have English fluent via phone. The teller will connect if not understand what you require.
Do you provide 12 month bank statement to immigration
In the big picture I don't think it's large% of foreigners here in Thailand.
Personally I don't get into the "get correct visa" Slaging.
For example with Oz pp I have 90 day visa exempt to Japan yet I need to Obtain 30 day tourist to get into Vietnam. I just accept the rules.
If there's a way to bend em then fine.
The thing is the OP has tickets to Thailand on April 7 and not clear if required docs in place to make Non O marriage e-Visa application.
Obviously obtaining the Non O prior to entering Thailand was the best option.
As it stands he want to
1. Lob in Bangkok for few days and open bank account and also buy a car. Answer No and No.
2. Go to Samui a d obtain a Non O marriage. Answer No.
3. Obtain an agent Non O retirement. Answer No (he is 44).
As you pointed out he can obtain 60 day extension to visit wife.
Perhaps exit Thailand at some point and obtain the Non O.
That's correct.
Also for those without a Thai bank account then if you obtain the Non O prior to entering Thailand you will be able to open a Thai bank account.
That of course in necessary to obtain 12 month extension.
If you are doing "bank to bank" Transfers then they will show as international in your Thai bank account.
Many guys in Thailand use companies such as WISE and sometimes transfers are not show as international,
That's the multi entry Non O visa valid for 12 months.
That is no longer available.
