I booked this bike tour for my family with a coupon. So with the significant discount, I felt less upset than I would have been if I had paid full price.
Problems? Let's start with the website which stated "Reservations must be made in Advance". I called ahead of time and was told by the person who answered that reservations are actually not needed and to just show up in time. I arrive, show my coupon, and the clerk behind the counter immediately asks if I made a reservation! I tell her what I was told and she turns around and asks another employee who also says I need a reservation! I was getting a little upset but to their credit, they redeemed the coupon.
I've been on a lot of city tours in many different cities and I expect the guide to be extremely knowledgeable, filling in details about the history or the culture you would not be able to get easily on your own. Unfortunately, our guide was none of that. We rode at slow speeds for about fifteen minutes at a time, got off, and then he would give a one minute introduction of the site which basically consisted of the name of the location and when it was built. Nothing that you could not easily find out on your own. For that reason, you might as well just ditch the guide and ride around by yourself.
The only reason I am giving this two stars is the price and the quality of the bikes. With the coupon, it really wasn't much more than renting the bikes alone and the though the bikes weren't new, they were very well maintained which made riding them a pleasure.
