Alternatives to Bangkok for taking a rest while between jobs

[AlphaCanadian]

A few years back I stayed in Chiang Mai for a few months while I was in between jobs. I loved it.

 

For a change of pace I decided to try Bangkok this time around. Bangkok is okay but I will not be returning to work for a few more months and it would be nice to try a new place.

 

I have considered going back to Chiang Mai again.

 

What I am looking for:

 

-Quiet and not too much noise pollution

-Being close to a beach is a bonus

-One of the reasons I chose Bangkok was because I thought I might need a tutor to help me with my pre cal math course (a large population so presumably more teachers/tutors). So far I have not needed tutor support however being in a place with a decent population in case I need this is a bonus.

 

I have considered Krabi.

 

I am not restricting myself to Thailand but I plan to stay in SE Asia.
