Soneone else mentioned only 1 day hotel booking needed for the 60 day visa, and that was OK, same with no return/ongoing flight needed. Presume I will need 60 days if insurance to go with my visa, which I would need/want anyway. Thailand pass requires 30 days ins if you arrive 30 day visa exempt (I believe).
I have 3 months from approval to enter the country with the 60 day visa. As I may still move my flight back a bit, I didn't want to pay insurance/hotel until I am sure what I am doing.
