I've been to Nassau a good bit and I'm a little weary of that port, but there are still things to do.
If you want a walking tour, Frommer's Guide to the Bahamas offers up a wonderful route. My son and I did this on our first cruise and had a really good time. We ventured off the path and found several little out of the way shops and restaurants with NO other tourists around. If you do a walking tour, don't forget Queen's Staircase, which will take you to Fort Fincastle. It's the highest point on the island and has a wonderful view of the harbor with all the ships.
I also recommend taking the #10 bus (you can get one at the terminal) and heading to "Fish Fry" for lunch. Any bus or taxi driver knows this place. We had a wonderful (fried) fish lunch and sat for hours on the outside deck overlooking the Fish Fry area, which on certain nights of the week is where the locals hand out to eat, party and socialize.
We also like Cable Beach. Resorts are more than happy to let you walk right thru their front door and lounge on the beach for free. There are wonderful little beach bars (all belong to the hotels) and even a few vendors.
Last time there we parasailed from Cable Beach. It's a blast!
