Redcar, I was about to respond to your post regarding your mobility at Centre Parks, when I saw that GrannyGravy had the answer.
Our DD & family have been a few times with her in-laws. They have hired various bikes, including trikes for both children & adults.
(Our DD was never a "natural" cyclist, but for several years now, has done the school run on a cargo bike in Cambridge!)
We are lucky, (albeit weary!), to have DD & children with us during half-term.
It's my birthday today, how these years have flown, if I make it to next year I will be 80..!!
Warm thoughts for you all in soop's lovely friendly kitchen. x
