If you have a physical disability, the USA can be an accommodating place. The Americans with Disabilities Act (ADA) requires that all public buildings, private buildings built after 1993 (including hotels, restaurants, theaters and museums) and public transit be wheelchair accessible. However, call ahead to confirm what is available. Some local tourist offices publish detailed accessibility guides. For tips on travel and thoughtful insight on traveling with a disability, check out online posts by Martin Heng, Lonely Planet's Accessible Travel Manager: twitter.com/martin_heng, or download Lonely Planet's free Accessible Travel guide from http://lptravel.to/AccessibleTravel.
Telephone companies offer relay operators, available via teletypewriter (TTY) numbers, for the hearing impaired. Most banks provide ATM instructions in Braille and via earphone jacks for hearing-impaired customers. All major airlines, Greyhound buses and Amtrak trains will assist travelers with disabilities; just describe your needs when making reservations at least 48 hours in advance. Service animals (guide dogs) are allowed to accompany passengers, but bring documentation.
Some car-rental agencies, such as Budget and Hertz, offer hand-controlled vehicles and vans with wheelchair lifts at no extra charge, but you must reserve them well in advance. Wheelchair Getaways (www.wheelchairgetaways.com) rents accessible vans throughout the USA. In many cities and towns, public buses are accessible to wheelchair riders and will 'kneel' if you are unable to use the steps; just let the driver know that you need the lift or ramp.
Most cities have taxi companies with at least one accessible van, though you'll have to call ahead. Cities with underground transport have varying levels of facilities such as elevators for passengers needing assistance – DC has the best network (every station has an elevator), while NYC has elevators in about a quarter of its stations.
Many national and some state parks and recreation areas have wheelchair-accessible paved, graded-dirt or boardwalk trails. US citizens and permanent residents with permanent disabilities are entitled to a free 'America the Beautiful' Access Pass. Go online (www.nps.gov/findapark/passes.htm) for details.
