Best sites for taking the woofers...

Hi Fellow Doggy Lovers, I would love to hear from other dog owners about their experiences of different club sites/CLs/privates sites and to hear about which ones they have found to be good for dogs.  We are new to caravanning and have two lively and lovely 10 year old cockers spaniels, Nelson (aka The Pesky One) and Wellington (aka Welly Boots) - we love going for a good old romp during the day, but also need to use sites where it is safe and easy to go out for a QUICK blast first thing in the morning and last thing at night.  I have read lots of individual site reviews but it would be good to hear recommendations.  We went to the show this weekend and ordered a Thule awning (very excited) and b*gger me we have booked onto about the only site on the network for Easter where you can't use awnings (Old Hartley!) so am thinking of trying to book an alternative.  All suggestions welcome :-)
