We will be flying to Bangkok (Don Mueang airport) next month from India with European passports. From the immigration website I see an e-visa isn't available for us because we're already in Asia. What is the maximum length of stay we can do in Thailand on a tourist visa? We would ideally like to stay 3 months. We have young children so it's not possible to travel long distances to embassies for example. Thanks in advance for the advice, I'm very baffled right now 🙏
