How not to waste Holiday usage

I have a month paid holiday leave from work in July.

I have to take it then as I work in an education job. 

Any suggestions as to where to go with not a great deal of money?

I also don’t know who to go on holiday with. 

I’m not sure I manage my life well. 

I have never managed to use holiday time successfully. 

I don’t want to end up wasting that ‘precious holiday time’.
