I was really impressed with Snakes & Ladders when I took my 19 month old daughter a few weeks ago. The cafe was in a good location so parents could keep an eye on their children and there was a special toddler zone for up to 2 years. This meant there was no pushing or shoving for my daughter and she loved the little ball pool which she slide down the slide into (again, and again, and again!) and the little bouncy castle. They even had some ride on toys which she loves at the moment.
The 2-5 zone was fairly quiet when we visited and but I couldn't drag my child out of the toddler area anyway!
There seemed plenty for slightly older children too including a big playframe with bouncy slide and electric motorbikes.
It was easy to park right outside and I think it was good value for money. read more
