<human>: I just booked a flight to Bangkok from June 7 - 28.  I am a 28 year old single canadian male and will be travelling with my buddy of the same demographic.  My brother is a journalist in Phnom Phen Cambodia and I'm going to visit.  I do not have any accomodation booked, nor do I have any plan as to where I will be going.  I am thinking about staying in Bangkok for about a week and then renting scooters or something and travelling around to different parties and islands, etc.  Not too sure if I want to go to Phnom Phen or not.

Give me the gist of the text in a nutshell
<bot>: If anyone has any pro tips on accomodation in Thailand, where I should go and what I should do over 3 weeks would be great.
