Right UK people,

Need a hand here - a group of mates have put me in charge of organising a Holi celebration somewhere in the UK. I'm going for the basic 'lets go mental and chuck colours on each other' theme - but anyone know where I can hold it? Ideally looking for somewhere that's easy to clean up afterwards, and with shower/changing facilities (so I'm thinking of some sort of sports centre) - does anyone have any suggestions? We can do this any weekend in March, and pretty much anywhere in the UK (everyone is spread out all over the country anyway).

If you've got any suggestions, please let me know. And no, my back garden isn't big enough!!
