I would strongly recommend taking your own lightweight wheelchair if you can (such as a Breezy). If you rent a wheelchair there you don't know what you will get. Generally it will be a heavy E&J chair that may not be in very good repair, and often has solid tires that feel every cobblestone in port. It also may not be the correct size for you or have the right features. If you need a chair, invest in one you can rely upon. Most insurances will cover at least part of the cost.
