What is the best way for a Spanish tourist in Thailand to extend their stay after a 30-day entry stamp?

A Spanish traveler in Thailand who wants to extend their stay beyond the initial 30-day stamp has a couple of viable options. They can either extend their current stay by 30 days for 1900 baht and then take a visa run to a neighboring country (like Laos or Myanmar) to obtain another 30-day stamp, followed by another extension, or they could leave for Laos to apply for a tourist visa directly, which can also be extended. Both options are feasible, but the latter might provide more flexibility.
