Look on the CC website and you can see what facilites the CLs have to offer. We use the on-board facilites most of the time anyway, so are not too bothered about toilet blocks - have you tried using yours - much better (we think) to step out into your own surroundings. You can run the Truma water heaters on both gas and electrics at the same time and this gives very quick recovery of hot water. We take two 8 litre jerrycans and have them next to the aquaroll so have over 40 litres of water to go at - plenty for two.
Dare I say it, but some CLs are adults only which means no cycling, ball games, small children waking early etc. Don't want to start the whole controversey again, but it's a thought.
