We used the Hop on/Hop Off. If you know exactly where you want to go and when it is not the best solution, but we initially just rode it all the way along its route and listened to our tour guide, and then made a decision about where we would first like to hop off from that. We also did a riverboat cruise, which was nice. And one night we ate at Manning's, and as it happened Archie Manning was present, so we thought that was pretty cool. There was a little sort of tucked away steakhouse we went to, I think it may be called The Star or something similar. We probably wouldn't have wandered in there if the owner had not been out on the sidewalk encouraging us to come in. One of the best steaks I have ever had, but definitely not a place if you want atmosphere. Lots of places to hear live music too.
