E vs PE on A330

Hi guys,
Just after some opinions if you don't mind.
Soon to be travelling to St Lucia on the A330 and am thinking about upgrading to PE. I just wondered what people's thoughts were about PE on this aircraft compared to Econ and if it is worth the additional cost? I know I am the only one who can answer the cost part etc, but I will be trying my best to secure an exit row seat in Econ and really asking myself the question whether it is worth it?
Another point, for two of us to upgrade to PE, it's £1150 return( this I won't be paying) but it was £600 a few weeks ago and having checked flight stats, PE is wide open, so is there a chance this upgrade price may come down again?
Thoughts etc appreciated.
