Zion is awesome, but if you want the most out of it, you definitely need to be capable of hiking the more difficult trails. There are a few great easy-ish trail, but most are at least moderate difficulty and the best are hard. With my wife and daughter's limitations, Zion was great, but I left wanting more. We were able to do about a half mile of The Narrows before my wife lost her balance and dinged her knee and we had to turn back.
Was also bummed that the first 2 nights had amazing sunsets that I wasn't able/chose not to shoot and our last night ended up being lousy with lots of cloud cover. Got a few cool shots though and a double rainbow I'll post eventually.
ETA: The deer and squirrels at Zion are way too used to people. There were 5-8 deer on the front lawn of the lodge every night and they were within feet of people. I walked passed a squirrel that was clearly hoping for some food and was on a wall next to the trail. I am 100% positive I could have reached out and grabbed him (and probably got bit). We did see a red fox run around the front lawn the first night which was pretty cool.
