I did. we went and stayed in a yurt for a week, and I did take the cloth went to laundrette and washed them halfway through the week and dried them on makeshift line outside yurt.
my reasons for doing so: very eco-holiday, and couldn't bear the thought of disposables lol none of ds2's trousers fit unless cloth nappy underneath where to put poo-ey nappies whilst staying in yurt???
no - have decided to use disposables when on holiday.
Don't like them though - have only been away for weekends so far and am always glad to get DS back into cloth nappies. I think if I was going for a length of time and had access to a washing machine I would take the clothies - like when we go to Australia (to MIL's) in October for 3 weeks. Camping is a bit tricky though.
