I would always go for a bounce/slide combo as you can keep a flow going with the kids. If you just have a bouncing area, it can get congested and you're more likely to get injuries through collisions etc. Good luck!
Party in our garden which is not huge. Can fit in max 20'x15' inflatable Would 6 year olds get more out of a slide, bouncing area or combo? ? worried about maximum numbers bouncing at a time Confused and indecisive 😕
