Crunchie
We've all enjoyed Point both times we've been. Site is quite spread out with a playarea near the main entrance. On-site shop is quite good - have a bakery that bakes fresh baguettes/croissants daily. Although we used the on-site shop daily, we did our main "bulky" shop at a Champion supermarket which is about a 5min drive.
Benodet itself is quite pretty - beaches are lovely and they have little "kids clubs" with bouncy castles/swings etc etc for them to play on. Benodet beach is about a 5/10 minute walk from the site but there is a beach across the small road from the site - lovely with rocks and rock pools. My kids spent hours crabbing
The waterslides are only open from 2pm until the pool shuts at 7pm. There is a bar which opens at 4pm which has nighttime entertainment. Couldn't tell you what it was like because we never went in there - we spent most of our evenings drinking with our neighbours Kids were all playing out together etc.
Can recommend the restaurant in Benodet on the seafront - can't remember what it's called but it's green
Also recommend visiting Quimper (about 15km away) beautiful town with a lovely Cathedral and lovely little cobbled streets. Also went to the Aquarium at Audeirne which the kids really enjoyed.
If your older child is into "kids clubs", my 2 loved the Funstation clubs - at Pointe, they split them into ages - 4+, 7+ and 10+. Did lots of activities - football/arts/treasure hunts/water fun etc etc.
I'm trying to think of other stuff - can't think, let me know if want to know more. Which port are you thinking of travelling to? We went to Cherbourg - journey from there to Benodet was about 6hrs!
This year, we going into Caen - journey time is only 3 hrs hopefully !
