Thanks, everyone! With the Southbank Uni Sports club http://www.lsbu.ac.uk/academy-of-sport/activities-for-kids/school-holiday-sports-camps we exchanged few emails and that's my fav.so far. Foresters sound great (my kids do Woodcraft) however the website says Holidays 9.30 ? 12.30 or 9.30 ? 2pm and I need a full day. I also found this http://lemonartlab.com/shadwell-club/ which is short trip by overground from New Cross and looks great. St Dunstan's College in Catford is running Supercamps https://www.supercamps.co.uk/ which are looking interesting too. I was looking at PGL residential camps out of interest but these run from May over the Summer mostly. Anyone has got experience with these?
