So as my plan stands now we'll be visiting Hoover Dam in the afternoon, then heading to the Stratosphere for an evening hour or two before heading back to Downtown. I'm old-school and I do maps, not GPS. My questions: (1) we'll be coming back north through town on the 515 obvs. What exit do I want for the easiest route to the Stratosphere? (bonus points for keeping us out of neighborhoods we shouldn't be in.) (2) we'll need to stop and gas up the rental car before turning it in. Easiest place to do this either before or after the Stratosphere? Thanks!
