Sorry, I have to agree that Jakes isn't as good as some other venues - such as Monkey Mates.
Parking is very limited, though Jakes have arranged with Pantiles to permit parking in Pantiles carpark, a very short walk away.
Children liked the playframe, though to me it does not seem to be the biggest around. Playframe is designed by SPI, so the slide can be climbed by children! Both times I've visited so far, no staff have been monitoring the slide, and some parents don't keep their an eye on their children, thus you have some children climbing the slide.
When busy it can be very hot at the top of the playframe, though went during the week towards end of term, and it was much cooler. So amount of human bodies seems to make the difference.
Big benefit for me though, is that I can walk to the venue. They have a discount scheme if you walk there, or come via public transport.
