What are my options for entering Thailand after a SETV denial in Hanoi?

I just got denied a SETV in Hanoi. I have had 4 SETVs back to back so no surprises there. They just flipped through my passport and said no on the spot, so no application made and no fee paid. There are no visa exemptions in my passport. No land border crossings either. I live in Chiang Mai. I only need one more entry into Thailand (30 days is fine).

Would my best bet be to fly to Laos and try to get a visa exemption at a land border crossing? If my chances are good I might try this. I’ve read a lot of posts here but would appreciate some advice. Thanks!
