If you aren't in a rush, the shuttles (all are about the same) charge $7.50 one way. Sometimes they wait until the shuttle is at least half full before they take off, so you can wait 5 minutes or 20 minutes before they head for the hotels. Usually more like 5-10 minutes. Also, you might not be the first one dropped off, but that never bothered us. We kind of enjoyed the "scenic route" of different casinos people were going to.
Anyway, you don't have to worry about being long hauled or traffic running the meter up as with a taxi. One price, and pretty low. Cheaper even than Lyft or Uber, except that you might get a free ride the first time. We haven't done either, as we only have flip phones. But I read where Uber and Lyft are both instituting systems that hook up with any kind of phone, to capture the old foggy population like us. Ha.
