My first take was to take tours with a company like Brewster or whomever in all 3 cities. Then I started readling reviews about the GyPSy guide here on tripadvisor. I started thinking that perhpas I would not do the local tour guide thing and do it myself using one of these devices. That way and lake cruises in Banff or Japser,,,or any other type of things that are thrown in with the local tours could be done on my own time, not theirs . It would seem this device gives you your own personal type guide (except for you can't ask questions) and I would be able to use it the minute I left the airport until I returned.
Aside fomr the comments on tripadvosor, does anyone have input as to whether this is work the price or not.
