Can I clarify which “Standing Jake” you are referring to? Did you mean the initial one with lady Rainicorn?
With the round Jake shape inflatable, we don’t necessarily need to hang this and we are OK with it resting on the ground. It will just require some supports to prop it up. Example images below – as you can see, these are pegged to the floor.
The booth size is 10x10, however the inflatable will only take up part of this (about ¼ of the space). I have attached the floor plan for your reference.
It would be great to hear their recommendations on size within this booth.
