Six of us were in a group between cruises out of Miami port. My wife set-up a Segway tour with a private company because nothing like that was available with Carnival Cruise Lines.
The guy who took us out was great. They take cash only at $95 per rider for approximately 1 1/2 hours. The company SegwaySouthBeach.com (954) 804-0253 if you want to book. We met him at Lincoln Road at the bottom end near the beach and across from the Ritz Carlton.
They are a smaller tour company with only 5 segways, but he is able to get more depending on group size. Its better to go with a company like this, as they give you training needed and get you on your way quicker than some of the larger groups in the area. He pointed out as we went by some of them, and you can waste time if group too big, as they tend to book.
If you havn't tried the segway, you should. It's a blast. This is the second time my wife and I tried it. She caught onto it pretty quick and she is very nervous about those types of things. She wants to do it again, it was so much fun. The others in our group had no problems, even though they never tried one before.
I would recommend this company as they showed us alot of south beach and gave us lots of information about the area.
They also let us try a segway that didn't have handle bars. Amazingly, it was alot of fun, even though it looked unsafe and hard to drive at first.
