Your web site (and those of most of the other agencies that you search for the best rates) do not make clear whether hotels have rooms equipped for the physically challenged, and does not make it possible to make a reservation and be assured that such a room is held for the customer's arrival.
The only alternative is considerable web searching, and then phoning the hotel direct to make a reservation. This usually results in an offer at rack rate, i.e. far more than the best rate available online.
Surely this is discriminatory in terms of what is required by the Americans with Disabilities Act and similar legislation in my own country (U.K.)?
What steps are you taking to ensure that the physically challenged are not disadvantaged and can use your web site to obtain the same advantage as others?
