I can confirm Melbourne Australia Thai Consulate - will grant Multiple Entry Tourist Visa (METV) to Americans (probably anybody else also). They asked for my Australian Visa Grant Letter (a Australia visa thing), proof of funds - credit cards will do, the cost of the visa, and flight information into Thailand. The did not ask about my proof of accommodations. However the lady helping me was "in training" and it may have been over looked. I had to wait two business day. No waiting at the office not for drop-off, not for pickup
