Tough question...I travel so much for work...sometimes I add one or two days to my business trips on one end or the other and have a mini vacation. My trip to Botswana with Mad Mike of the Discovery Channel was probably the most adventurous and the longest...two full weeks!
my most memorable vacation was when i went to mexico with my first real boyfriend. i was in college, he just graduated and he wanted take me an a vacation just me and him so we decided to go to cabo. it was so nice. we pretended to be newlyweds so we got the ultimate treat from the hotel. plus, we didn't have anyone bothering us, only people catering to us.
