My family and I (two adults, five kids) are USA passport holders and will be in Thailand for 100 days from Nov 3 to Feb 9. We're planning to fly to Laos for a 4-day trip somewhere in the middle, though I have not booked tickets to Laos. I was thinking to get a Multiple Entry Tourist Visa (METV), but I'm considering options since the METV costs $200 x 7 people = $1,400.
Can I arrive on a 45 day Visa Exemption, extend by 30 days for 1,900 baht each, then fly to Laos for 4 days, and then fly back to Thailand and get another 45 day Visa Exemption? That would make my total cost only $350 instead of $1,400. Does that work?
Also, how should I show proof of onward travel?
TLDR : Answer Summary
A family of USA passport holders plans to stay in Thailand for 100 days and is considering using the Visa Exemption scheme instead of applying for a Multiple Entry Tourist Visa (METV). They propose to enter Thailand on a 45-day Visa Exemption, extend for an additional 30 days, then travel to Laos before returning for another Visa Exemption. Comments suggest that this plan is viable and advise contacting airlines regarding proof of onward travel.
