Come in on 30 day Visa exempt and apply for additional 30 days from local immigration for 1900 baht. Or, apply for 60 day tourist Visa before you leave. Providing the country from which your passport is issued qualifies.
visa on arrival is a totaly different thing to Visa exempt and aimed at people with certain passports so allthough I dont agree with calling you names you are wrong.
I am not sure for the marriage extension but I believe you can spend the 400k. Another plan, which I am following, is to send back some or all of the 65k montly payments to the UK using Dee Money. They dont mind what you do with the monthly payment amounts they just have to show so you can also spend as much of them as you like. I know there will be transfer costs to consider but it might help your cash flow as you can use the same 65k for next month as you used last month. A friend did it for years.
Tony, I might be making some assumptions about your situation but I will attempt to put your mind at rest. You are transferring from banked 800k to monthly income of 65k plus each month right? As your current stamp was issued using banked money you must meet the conditions for it which are that

0 stays banked for 3 months after application and does not go below

0 for the rest of the year. To get your next extension based on income you must show 12 monthly payments of at least 65k showing on your statement as international or ftt. When you go to get your stamp based on monthly income the officer will check that you did not go below 400k as was required by last years stamp and that 800k was banked for 3 months after it was granted. So, you can not spend the 400k until you have obtained your next stamp based on income. I am currently in the middle of this process but I will leave 800k for the year to be sure and have a back up if things go wrong. I use Bangkok bank and wise for monthly transfers and so far they have all showed as ftt.
The Officers are not making up the rules they are simply applying them rigorously. Good luck.
