Hi,
Sorry, not been to this site but we used to own a chalet at Sutton on Sea. We ended up selling it and buying our caravan because the kids didn't like the place.
Without wishing to offend anyone, it's not really a place for kids but many elderly people seem to go there. Even the chippy had a defibrilator behind the counter!!
There is a nice little paddling pool and a couple of tennis courts. But you need nice weather for these. Beach is nice.
Sure you know Mablethorpe is nearby but it is a good couple of miles walk from Sutton on Sea. Parking in Mablethorpe can be a problem in peak season but it is a nice bike ride along the sea front promenade with a lovely little cafe along the way.
We too are looking for a site in the Mablethorpe area but don't know where to go. My 8 year old loves the old fashioned arcade in Mablethorpe and she can't wait to go!!
