Suggestions, SUGGESTIONS, Read All About It!

Ok friends, I need some help!

Poor me has only about 3 weeks off of school for Chinese New Year {school goes until the very beginning of July so don't even start on "it's not fair!" lol} and I plan on making the most out of each of these days in the only way that seems logical to me....TRAVELING!

Shoot me your thoughts, personal experiences, & opinions! 

I'm leaning towards Thailand, but Cambodia, Laos, Vietnam are also great contenders as well {ok let's be honest...any country that I've never explored is new to me...right?!?!}

Also, since I'm most likely traveling solo I'm leaning towards some type of slightly organized trip. Like I don't need someone spoon-feeding (or chop-stick feeding me for that matter) and holding my hand as I cross the street, but having English speaking friends and a loose guideline of what way's up would be greatly appreciated for my first time there!

Sooo, do you have any suggestions of travel companies you've  used or heard of?!
Any first hand experiences to share with traveling in Asia that might be helpful?!
or...Do you just want to fly on over and join me and we can ditch the whole tour deal altogether!?!?!
