Save the cash and use if for something more interesting.
I managed my own hours building, going where I wanted and when. I did try and add some sort of structure to it towards the end by flying a bit more accurately, but for the most I just flew to enjoy the flying. I flew overseas in several countries whilst on holiday, and went all over the UK to various places to try and get as much experience of different things as I could.
You have plenty of time on the CPL course to do what you need to do, so just enjoy your hours building and make the most of being able to pop out for a £100 hamburger !!.
