Should I take my x100 to Glastonbury this Summer...

Hi all

I have had my arm twisted and am off to Glastonbury this summer.

My initial view was not to take a camera, however all my friends (who know my love of photography) have said that I would be made not to!!

I own the following cameras, along with some consumer and pro' lenses:-

- Canon 5D MK II

- Canon 550D

- Fuji X100

There is not chance that I will take the 5D MK II, and there is little chance that I would want to the 550D.

So, the question is, should I get an extra few third party batteries and take the x100 or should I just purchase a cheap compact digital camera from eBay and just take that - it would cut down on the worry that I think I will have in taking the x100.

Please help!

Thanks all
