What if the hotel staff and Harry and Marv ever met?
As much as I love this movie--and the first film--I've sometimes wished that there had been an alternate version of this movie where the concierge and his team AND Harry and Marv squared off against each other. What if Harry and Marv had chased Kevin into the hotel when they saw the concierge chasing him?
Or what if, after Kevin pinched the supermodel's ass, he then ran back to the hotel, knowing that Harry and Marv and the concierge et al. were all after him and that both groups might run into each other and get distracted?
Kevin is a smart kid and may have known that there would be a stalemate between his enemies if he got them in the same space.
