Travellers with Disabilities
In general, this region is up to the legal standard in providing access to all in restaurants, transit and other public accomodations. The 1990 amendment to the Americans with Disabilities Act essentially prevents prohibiting access to public facilities for anyone, and this includes foreign travelers.
In New York, the Big Apple Greeter (www.bigapplegreeter.org) will provide you with a list of accessible activities and even match you with a volunteer to help you get the most out of your visit.
The US Department of Transportation's Disabilities Resource Center provides a handy document for travelers with disabilities (www.transportation.gov/drc/travelers-disabilities-information-and-resources).
Traveler's Aid (www.travelersaid.org) has a link on their website to specific transportation carriers and their policies regarding disabled passengers.
