I could try for another tourist visa in Vientiane, and if not try for 30 days visa exempt entry. Or instead then fly/travel to Hanoi from Laos to try for a tourist visa.
Wow I see. Didn't know people go there for visas. But again if I arrive back in Don Muang, likely they will ask for all the proofs now I think after this many visas. And I understand it happens more in Don Muang.
If I wasn't allowed to apply for another tourist visa in Vientiane, seems likely that I also wouldn't be allowed in for example Penang, Malaysia.
Or you think it would be fine there?
If I flew into Don Muang on a 6th tourist visa though, I think would be a high chance of them asking for proof of funds/onward travel/accommodation etc.
