Most disabilities shouldn't stop anyone from traveling. There are more options and resources out there than ever before. Most major hotels in the large cities of Vietnam -- Ho Chi Minh City and Hanoi -- can accommodate travelers with wheelchairs, but hotels in rural areas are unlikely to provide such services. Ramps are uncommon.
