Hands down Deckerts, we have used them for my parents on sevreal trips. Not sure where you are staying, but on our trip last week I had some medical flares midway through our trip and it was either order an ecv or stay in the room (yup it's a little humiliating for a bit). Obviously staying in the room was out. I was by the bathrooms by it's a bugs life when I finally gave in and called Deckerts to order a third one for myself. It was a two minute phone conversation and they had one already at the DLH bell desk that they told me to go grab. If was perfect,charged and really a life saver. So not only are they great but they leave a few extras at the onsite hotels for guest in quick need.
