Let me take a minute to discuss Ko San Road.  It is basically backpacker town (like china town).  If there is ever a question as to where to take tourists to find a guesthouse in Bangkok, the answer is Ko San Road.  This sounds cool right!  Meet a lot of cool travelers no big deal.  Well along with tourists comes carts selling everything imaginable from cloths to fruit shakes to dried squid (very popular in Thailand) to tours you can even get your hair dreaded.  The icing on the cake is everyone is getting drunk. 
To make it more intense it was 6 am when I was dropped off.  There was one place open so I sat and had a fruit shake with another woman also traveling alone with one small backpack.  All I wanted to do was sleep but nothing was open so I sat waiting for everyone to wake up.  There were several other people there some still drinking (or maybe drinking again).  I just wanted the pharmacy to open.  That sauna I viewed as lovely and relaxing was now seen only as the annoying source of athletes foot.  Once everything started to open I took care of my feet and then tried to buy a bus ticket.  Guess what time the bus was………NIGHT BUS!  I can hear the creepy horror film music now.  OK don’t panic, remember to breath.  Sure I’ll take that bus. 
This is the point that you are all glad you are not traveling with me.  I was cranky!
Now I want to mention that I should have bought a room for the day, slept and set my alarm for the evening bus.  That would have been the smart thing to do.  Of course trying to save $ and being slightly delirious from the previous two night busses I didn’t.
