I think the poster has zeroed in on a basic problem. Situations may vary; but for those with limited mobility, the distances that one must walk in many ports of call to get from ship to terminal/buses/taxi is a challenge. Whether it's charter buses, shuttle buses or golf carts, lots of us could use the service. On each of the five O cruises we have taken, I have skipped one or more port of call because I didn't want to face the challenge of the long, painful walk. I don't use a cane or a walker in the "real world;" so, looking at me, you wouldn't think "mobility issue." But, I have enough metal in my back, hips, legs and ankles to make me bionic. As many others have noted, Oceania's demographic is changing. We are aging and the company would do well to adapt to our needs.
