Do I need a Guardian Visa if I plan to be in Thailand frequently with my kids' ED visas?

Hi Guys,

See if you can help with my case, pls.

Myself and family (wife + 2kids) are moving to CM in June/July. Our plan is to get the kids ED visas and we get the guardian visa.

Now, I will be flying in and out of thailand at least twice a month. Do you think i need a guardian visa, or i can keep my tourist visa and, in the event of being stopped at immigration because of multiple re-entries, explain my situation to the officers. I know I can get the guardian visa. But wanted to avoid the transfer of 500k if possible.

Thanks!
