I leave tomorrow and used Kenny to rent 2 carts. Everything went perfectly.
he arrived when we told him we would be checking in. The carts were speedy, but not too fast. We had rain shields, which came in handy tonight. I didn't notice any other carts with these.
Just a tip, bring something to attach to the cart to identify yours from all of the other white carts. Kenny recommends this because they can be tough to tell apart (his carts aren't numbered like FW carts). I used a small mickey water bottle snuggy because it clipped t the frame nicely, and it was disney so it fit right in.
