+1 to both those places, assuming you flew into Metro, you could hit tropicorium on the way out of town. Lansing is a bit of a hike from Troy. Everything else I would say is run of the mill, though Oceans and Seas is pretty nice when it's clean. Stingray Bay has a rare breeding pair of freshwater rays and nice clean tanks. Occasionally they get something interesting in but I haven't been there in a few weeks. The economy has been rough on the shops around here. Nobody is keeping rare stuff around on the hopes that someone will impulse buy it. I hope you have a pleasant stay. Then you can tell your friends, "Well, it wasn't as bad as Cleveland." Totally kidding about that I love Cleveland.
