My husband and I are flying in late--about 11 pm--for a last-minute weekend trip soon. We've been weighing the option of taking a taxi to/from downtown then walking or bussing to places (I have limited mobility due to a sore Lyme-disease weakened knee). Or we're considering renting a car so we can have it if we decide to drive out to Cape Spear, up Signal Hill, & to Quidi Vidi. Our main hesitation is driving from the airport so late in an unfamiliar city (we're staying close to the Duckworth). Any recommendations? Or observations of how drivable the city is this time of year? Thank you!
