We are interested in using the bus when in Vegas for 3 days. I've read posts here and looked at the RTC website, but am still confused. We want a pass for mainly the strip, possibly going to Freemont, and will even consider taking public transit from the airport to our hotel (Harrahs). My questions: 1) Do I need a basic 3-day pass for $15 or do I need the "premium" pass for $20? 2) Is it easy to get to Freemont with the bus? 3) How hard is it to take public transit from the airport to Harrah's? If I order the pass in advance and it is straight forward to take the bus to our hotel, we would certainly consider doing that. Thank you.
