Two 24 yr old Males travelling to Thailand for 15 days. What are the must see cities?

<h3>Two 24 yr old Males travelling to Thailand for 15 days. What are the must see cities?</h3>

A buddy of mine and me are travelling to Thailand for 15 days in search of nightlife, exotic food, beaches, nature and of course a little bit of Thai history. I know 15 days is not even close to being enough time to completely scratch our itch, but what are 3-4 cities that we should definitely visit to accomplish what we seek? Any assistance would truly be appreciated.
We're looking to spend roughly $ 3000 USD - $ 4,000 USD between the both of us. Thanks again!
