When a ranch calls itself 'Resort' then the accommodation standard comes probably close to a hotel.
A good definition is: Resort Ranch == Comfortable hotel in 'western surroundings'. That means that a guest will find horses here and he can go for ridings. In addition a Resort Ranch is usually family oriented and has a entertainment program for the guests.
Not to forget ammenities like sauna, pool, tennis and may be golf course.
The price for this kind of stay is mostly higher than on dude & guest ranches or working cattle ranches.
