We rented from Disney in July. Fortunately, Fish Creek Rental was able to fix our bikes both time we had problems. We just happened to be right by them when we had problems on two different occassions. They also let us borrow one of their bikes until Disney could bring us a replacement so we were not waiting. I do have to say that Disney covered our bike rental for the week because of our problems.
The one nice thing about Disney is that they have the KiddieCaboose tag along if you'd be needing something like that. The rental at Fish Creek had a very different tag along which didn't have any type of enclosure.
Fish Creek did tell us they would deliver and the bikes would be waiting for us upon check in. However, the Disney bikes were more comfortable than the Fish Creek bikes.
When we go next year, I'm not sure what we will do. We'll still need the tag along so we'll probably rent from Disney but we'll DEFINATELY have our cell phone with us. We could have had a long walk back to the resort had we not broke down where we did.
Have fun. I can't wait until we go next summer.
