What are the best options for extending a stay in Thailand on a tourist visa?

Hey everyone!

I hope you're all doing well. I wanted to reach out on behalf of my friend who is currently in Thailand on a tourist visa. She initially obtained the visa in March and extended it until the 4th of July. Now, she's exploring her options to extend her stay in the country.

Since she resides in Bangkok, she's contemplating a border run to Cambodia. However, this would only grant her an additional 30 days, with the possibility of another 30-day extension. On the other hand, she's also considering flying to Kuala Lumpur to apply for a new tourist visa, which would allow her to stay in Thailand for another 60 days, with the chance of a 30-day extension.

We're seeking advice from those who have been in a similar situation. Which option do you think is better? Are there any other ideas or experiences you could share? Your insights and recommendations would be greatly appreciated.

Thank you so much in advance for your help!
