I have been alot but not for about 10 years and cannot remmeber any of the parks. I have looked and looked at the website, but wondered if anyone had any recommendations for a more toddler friendly park? Have looked alot at one called "beg mel" (?) but there is so many more Only things we really 'need' a re toddler friendly, generally child friendly, close to a beach and lots of water slides (for DS1, honest ) Thanks so so much if you can help - first holiday as a family and I want to get it right

Never been before but off to La Garangeoire (query spelling) this August with a 4 year old and 1 year old which ticks most of those criteria (including water slides - beach is a drive away). Generally got a good write up from other MNers who have been there.
