What are the best border crossing options for Brazilian passport holders seeking a 3-month visa exemption in Thailand?

dido - be careful to pay attention about information specific to Brazilian. I am impressed you've done so many back-to-back visa waivers. Always we hear about the people that hit a snag -never the success stories. Normally, I fly, have visa, have proofs: accommodation, funds, outbound travel. I cheap bus tickets for outbound travel.

Good luck ( US passport holder by the way).

we do NOT get unlimited border runs nor exemptions.

Also Thais cannot visit "south america" for 90 days. They can only visit the 5 countries that hold bilateral agreement (Arg, Chile, Peru, Brazil and Korea)

If a Thai goes to Mexico or Uruguay they need a Visa as its true the other way around

I am ARG and even tho i do not use exemptions i an also admin of a group of argentinean people in TH and they get denied everyday just like any other nationality lately.

Last week a couple with a 2 month BABY was denied coming back from KL through DMK contacted me via pm crying etc... sad

My advice would be stay away from big airports.

Nong Khai seems to be a good choice, always been a friendly border for these type o' things.

Plus they cant deny and "send u back home". Worse case u re enter Laos and fly Vientianne somewhere else... or try next day....

With more than 4 consecutive stamps (more than a year inside no breaks) i WOULD expect to have problems tho i wish u good luck.

I don't know what the current situation is for Brazilians at Mae Sai. I have heard reports of at least one other visa waiver country NOT being allowed there. You need to make sure that information you get is specific to Brazilians, or at least other 90 day visa waiver countries (like Korea or Argentina). That a French or an Irish person has no issue doing two border bounces a year at Mae Sai has no bearing on whether you can as a Brazilian.

Nong Khai, Mukdahan, Mae Sai, and Padang Basar (via Train) are all really easy. Entering via Chiang Mai or most other airports like for example Surat Thani which I did last week is also very easy. Avoid Bangkok, Phuket, Koh Samui, Krabi, and Poipet by land. p.s: Never use an agency, you don't have a higher chance of success, there no point unless you are a total newbie.
