Would vibrams be a good bet for festivals?

I just went to Glastonbury. It was great... but most of the place was covered in wet mud half a foot deep. Everyone wears wellies, pretty much without exception. Walking miles a day in heavy rubber wellies (plus trying to dance in them) got pretty exhausting and I thought there had to be another way.

So would vibrams be a good bet here? I'm never come into physical contact with them... would they mind being soaked in wet mud for five days straight without disintegrating/cracking? Would they be easy to clean? Would they stay warm?

I was thinking of getting the watersports types because it seems akin to spending a few days constantly wading around.
