Then you don’t need to apply for any visa, you can just enter on a 60 days visa exemption. Formally you’ll need a ticket out of Thailand within 60 days. Rarely checked at the immigration, but I know some airlines in Vietnam has been quite strict regarding this as it’s their responsibility to check if the passengers fulfils formal requirements. I know people only have purchased a cheap bus ticket out, but some airlines might require a flight ticket. If you go to a website it should be quite easy to purchase a cheap flight ticket as an example to Phnom Penh. It would be cheaper than to apply for a tourist visa anyway and you’ll be fine with all formal requirements.
