Can a hotel require a disabled person to stay only in specified rooms if the disabled person travels with a service dog?

Answer 1

No. "People with disabilities who use service animals cannot be charged extra fees, isolated from other patrons, or treated less favorably than other patrons." (See ADA business brief link below.) Requiring them to stay in a certain room when other guests are permitted other rooms would be treating the person with a disability less favorably than other patrons.
