Weeboy...Browns is absolutely correct and since Rob and I obviously know the route system well...we would never recommend taking 5 people via route taxi into Sav either.
Dependant on which school you're going to in Sav, it's not going to be easy to navigate a route taxi for 5 people...more than likely you'll have to switch cabs and this won't be easy in a busy town like Sav with 5 people...this could be overwhelming for your newbies.

You won't have any problem chartering a driver. Pick your fav driver, tell them what you want to do & negotiate a price & plan that work for all of you. We all have business or someone to visit in Sav, so there's always something for your driver to do while waiting for you...it truly will not be an issue for your driver to wait.
