My beginner girls loved it, but my older daughter was frustrated her last year there. She didn’t have enough experience to move up to the next group, but felt the entry level was repetitive.
The horse knowledge instruction part doesn’t change (parts of a horse, etc), so I wouldn’t do it for many weeks.
There is a show on the last day, and they make a big deal about the parents attending. It’s disruptive if you are using camp for childcare.
That said my girls would cry on the last day, because they missed “their” horses. I’m glad we did it.
