party bus // novelty transport recs ?

hi team

looking for any leads / suggestions for a good party bus company or know of a novelty way to transport people from one place to another in Brisbane?

organising a 50th for my mum and looking to get 20 people to the city (~30 minutes)..creatively, as a bit of a surprise

would do a party bus with lights etc but it's a bit tired, looking something fun/out of the box (or at least a good experience with party bus company) !
