Its very cute - I would suggest that you stand inside the entrance for a couple of minutes to let your eyes adjust to the dark inside of the building. Then when they walk you to "your car", you'll be okay and see that's its really quite light inside. The inside of the cars are lit up as well so he should be fine! Be sure to get him the special cup with the light-up ice cubes - they're extra $$$ but so much worth it!
