Has anyone done a 30 day visa extension trip Ranong to Myanmar and back to Ranong recently?

Did you use one of the longtail touts who hang around the pier? How did it go?

Also: What was required please back in Thailand, as I recall the only thing mentioned on the descriptive boards there was 20,000 Bhat, presumably in cash, but I suspect the well prepared will also have an onward ticket out of Thailand, and a hotel booked for the next night.

Thanks!
