What are the best options for extending my stay in Thailand after my 60-day entry visa expires?

Hi All, My 60days on entry will expire in March and I’m planning to go to both Krabi-Koh Lanta & islands there, and up to Ranong after… Can you advise if better to:

Option 1:

Cross into Malaysia for few days from Koh Lipe to Langkawi or other suggestion to get another 60days on the return trip back. In this case how long do I need to

stay on langkawi before entering back or is a day trip sufficient?

Likely it’s more costly option for the travel but I would get 60 days and no visa paperwork or cost.. right?

Option 2:

Renew my visa in immigration office in Ranong (before visiting Koh Chang) and pay for the 30 day extension? I’d have to go few days early to avoid the weekend when it’s closed and stay in hire there to get the Tm30 form.

… maybe there’s other good options you suggest too? Be really glad for advice based on your experience 🙏🙏
