hello! Sorry that I don't know what your country is? You may already know that Thailand has 3 season : sunny, rainy, cold (just average 20 degree in Bangkok city, but colder in North part). What kind of place do you like to visit : mountain, sea, or cultural place? I can suggest you the exact place you like to visit. People in Thailand is friendly, smiley as the alias "The land of smile".
Hope you may visit our country once, welcome to Thailand!
