OP, the place you attended is what's known as a "dude ranch". The horses are trained to follow the leader and most of the time won't even respond to the rider's commands if given. I'm glad you had fun, though!
As for some of the other comments:
Western riding is easy on people, hard on horses.
I think that's rather ill-informed. For one thing, in Western riding the horse is guided by neck-reining and leg/foot commands. It's much easier on the mouth than an English bridle.
Also there is no jumping in Western-style riding, which speaks for itself.
If you're referring to the weight of the saddle, that is really nothing to a horse.
Western.... concerns itself with riders not falling off, and being comfy for hours in the saddle. How the horse is using its body is far less important.
Not true. Roping has already been mentioned, but you should also check out reining, pole bending, barrel racing and other Western events. How the horse uses its body is everything.
Reining is as skilful as dressage, if not more so.
Western riding is great for beginners because it’s virtually impossible to fall out of a western saddle.
You could hardly fall out of a western saddle if you tried.
Ha, ha, ha, ha, ha, ha, ha!
It's more comfortable for riders too, surely, than bouncing on your bum?
If you're riding Western style properly you shouldn't be bouncing. You move subtly side-to-side with the horse when trotting.
