can't use tape to hang up decorations 😒

so we are planning our baby shower. WOHOO!!, anyways besides the stressful planning by ourselves the place we want to rent to make our party doesn't let people use tape, pins and staples to put up our decorations, some may be familiar with this stupid rule (we can use painters tape but no they said no) really? well does anyone know what to do about this adorable rule? we need to make this kind of decorations because those are the color we choose and theme  ⬇️
