They are not perfect, but they do provide value. My wife does not take showers more than once or twice a year; she takes a bath. Usually twice a day. This is a surprisingly difficult piece of information to find on hotel websites. Booking.com will at least tell you if the property has rooms with bathtubs.

I have resorted to making most reservations by phone, rather than Internet, because it’s the only way to be sure. I don’t like it, it wastes my time, but I have a specific person I can call out who flat-out lied to me if I get there and the room has no bathtub. That is usually enough to get the manager to upgrade me to a room that has the one amenity I specifically requested as a condition of booking.
