We have booked accommodation in Thailand for 89 days. We are Canadian and planning to arrive and use the 60 day visa exemption. If our accommodation end date and return flight are both 89 days after arrival is that a problem? We plan to do a 30 day extension but worry that the onward ticket already dated 89 days later will be a problem on arrival. We were in Thailand using visa exemption in January of this year and came home to Canada 60 days later.
