Can I re-enter Thailand for a new 30-day visa exemption after crossing the border at Mae Sai?

One question, can we do this cross border after 30 days exempt? Came begging of December by plane, and I'm wondering between doing torism in Chiang Rai and cross the border to have another 30 days... Thanks

And VIP just means bigger, more comfortable seats that recline. Good luck!

The Bus was not completely full, there were a few seats in the back near toilet. The “VIP” seats are only the first two rows of bus, and cost a bit more but still very cheap. I left at 8am from Terminal 2 Chiang Mai, arrived 12:45 in Mae Sai, songtauw for 15 baht over to border crossing by 1:15, walked across the bridge, left Thailand and turned in my departure card, walked into Myanmar, handed over my passport (they keep it), got my Myanmar day pass (10 usd), looked at some vendor stalls for 10 minutes, walked back across, got my passport when leaving and entered Thailand for my new stamp. Back on songtauw to bus station, left Mae Sai at 2:30 and was back in Chiang Mai by 8pm. If you do this, watch your time while over the border as there is a 30 minutes time difference Thailand-Myanmar. I almost missed my bus back.

On website you can choose location of your seat. Station is Terminal 2 across superhighway from Central festival.

Yes I took the VIP bus. I reserved a week in advance on the green bus website, and chose the option to pay at 7 Eleven (can be any one). Then I walked to my local 7 Eleven on the corner and showed them a confirmation code on my phone, and they printed my ticket which just looked like a receipt. I would recommend doing this to ensure your spot. And take socks and a jacket. The bus is 17 degrees.

And I came back to Chiang Mai via bus the same day.

It's not ilegal, it's totally legal.

no , nothing required.
