Glad my experience was able to help you !
SMD recommended gloves. Even if you don't do outright arthritis gloves, consider having a hand covering of some kind.
When I was at the Zoo, I found the material the handles were made out of was irritating my hands -- they were itchy and red wherever they touched, even though I had wiped them down.
My solution was to put on the sun protective "gloves" that I have, which both gave me sun protection for most of my hands, but more importantly created a barrier between the handles and my hands. Problem solved.
The gloves I used are these from Eclipse:

At Disney I usually wear the sleeves in lieu of sunscreen and have yet to get burnt or even tanned under them. Although you would think the sleeves would make you hot, I actually find I am cooler in the sun wearing them as the direct sun is hitting them and not my skin, and they will absorb any sweat which then with a breeze over them creates a cooling effect. The gloves work well when I wear a long sleeve sun protective top, though I have to check the "watch space" at the wrist because one or the other may ride up or down.
As someone who is immune compromised, the gloves also do a couple more things for me: they are a barrier when I touch things (e.g. door handles) and they serve as a visual reminder not to touch hands to face (even if you start to, let me tell you, pink polka dots or even cream gloves coming at you are a good way to make you stop and rethink what you were about to do without thinking).
