@Jun ******
you are not correct, you apply ONLINE, you get the confirmation and print that out, you go to the embassy and pay during the hours I mentioned, then you just wait IN Lao until you get the email stating the application is approved and you PRINT the attached PDF file because that is the visa.
So no, you go to the embassy ONE time to pay and then wait for the approval
Shouldn't have an issue showing where you're staying if you have that documentation.
Did you read the requirements for the tourist visa on the eVisa website
