Thank you so much for all that info!!! I'm definitely going to look into that tour. My friend found another we were going to go on but we might have to choose between this one or that one now. We kind of want to do just one whole day tour instead of a bunch of little ones... kind of just to see all the big tourist sites at once, because you HAVE to see them, and then if there's any we'd like to go back to and spend more time at, we'll have a whole week to do that
