I witnessed one of your drivers get out of their car at the yacht and beach club to hand a child a ball that had been kicked in the road. The driver could tell that the child was going to run out and get it. He handed the ball back and said "safety first" when the child thanked him. I thought this was very nice and showed me that your employee took his job serious and was not lazy.
This was the best thing for our week long stay at Disney. They text and call to confirm the order and when your food has been delivered. Totally eliminated the hassle of food shopping once you arrive in Orlando
I do not think any type of improvements need to be made. Was super easy and it appears you have perfected your service :)
