Thank you so much for sharing your thoughts. Unfortunately, my client does not want to use a wheelchair, scooter, or a cane to get around, but can't comfortably walk more than 25 feet, per his wife. I finally came to the conclusion that there were not really any ports or excursions that I could guarantee he'd be able to navigate without using some sort of assistance. But, all of this is great to know for the future. Thanks so much.
