Online info on Thai visas is generally out of date and not synchronized with actual requirements of Immigration at the Bangkok airports. In Taipei I scurried about to prepare documents for Visa on Arrival, following online instructions, and then after arriving I was told that those rules were no longer valid. All I needed was my passport (USA in my case) and boarding pass for 45-day visa exemption. So to celebrate I went straight to my favorite little restaurant on the first floor of Tharathip Mansion near Ari and Saphan Khwai stations. The best spring rolls in Bangkok! Delicious Chinese noodles-and-ham dish too...
