Hi there M.H.
We ended up at Camping Ter Spegelt at Eersel south west of Eindhoven - www.terspegelt.nl. Even the cheaper pitches - about 80 sq. mtrs. only 6 amp electric - have individual water, electric, T.V. sockets and grey water drainage - I paid 62.00 euros for four people for two nights with use of indoor pool complex thrown in. Three lakes. one for fishing and sailing ; no power boats allowed. One for swimming with water slides - one meter deep in bouyed off area; five meters outside that; surrounded by sandy 'beach'. Toilet blocks are exceptional. Plenty of play areas for younger children, adventure play areas, aerial ropeways in trees sort of thing for the bigger ones though these did not seem to be in use ( out of season perhaps ). Alas my party were not in the frame of mind - having been beaten by Sevilla - to use all that and after all the travel and late nights were lucky to get up for teatime let alone go leaping about in trees ! There were very few people there but I imagine it would get busy and noisy in August. Do have a look at the web site.
