It's a good way to see the major areas of the city. We did the all loops package. The 1st tour was really good (golden gate and sansalite loop), Betsy was a great tour guide, full of funny stories and informative about the areas we went through. So we had high expectations about the other tours and to be honest we were a bit Dissapointed. The guide on the downtown loop seemed more interested in telling us about where to eat than anything else, not quite the city tour we'd hoped for, especially as all the names became a blur by the end! But it was still ok. I've been on tours all over the place and would rate it as ok, and still the best and cheapest way to see the major areas on a short timescale.
