Has anyone ever gone on a riding vacation? I found a site, www.equestrianadventurer.com, that lists a bunch of ones that look really cool (especially this one - http://equestrianadventurer.com/EQA_view.php?tid=55 - an African safari on horseback!).

Are they really all that fun, though? Or is it just basically a trail ride and all you get to do is walk around for like an hour a day?
