St. Thomas is beautiful, but nothing is handicapped accessibal as we know it. I walk with a walker and it's difficult for me. Shuttle busses are really for people with good mobility, and 150 pounds or less. Don't try doing downtown, as the sidewalks slant and very rough. They have shops right at the main pier, if you're lucky enough to go to that pier for docking. Look at the brochures they give you on the cruise lines. Some will show wheelchair accessible. It's a decent indicator, but not always 100% accurate. I hope you make out OK.
