Thanks for the report.
2 things.
1. Better clarify your post to indicate the overnight was in Bangkok (in the middle of the outbound trip) and not Yangon (at the turn around).

2. Any way to do an immediate airside transit at Yangon? Any transit desks (or signage for transit passengers) before immigration? I’m doing this trip next weekend and still undecided on whether to overnight in Yangon or do a same day arrival. I have the evisa bought but want to save it for the return leg and not have to spend other 50 USD (because I expect the checking agents to ask for the evisa before issuing the USA ->Myanmar return leg boarding passes)
