Suggestions on Where to Drive around in a Limo in Mississauga?

For our graduation, we are getting a Hummer H2 Limo to drive us to our afterparty, the distance from the school to the afterparty is only about 15-20 minutes and we have the limo for an hour. Are there any suggestions where we could drive so we can stay in the limo longer? We're going to tuckers marketplace by the way for our afterparty, or somehwere in that area, any suggestions on where we can drive before we get to the afterparty?
