We're coming up the A1M tomorrow from London and would like to stop off somewhere around the Cambridgeshire section of the motorway for the children to stretch their legs. We could perhaps push on to Linconshire way. Any recommendations please? Needs gardens / playground and coffee facilities. Ideally loos but we can manage. No more than 5-10 mins off the motorway. Happy with "a really nice services". Any recommendations please? Thanks in advance 👍
