My 2017 Trip to the USA

I will be going to SFOG on the Saturday, last day of my trip. Do you have rush hours on a Saturday?

My flight is 22.50pm. What sort of time do you think I should leave SFOG to get to the airport for 19.50? I'm thinking of about 17.00 - 1730.

Atlanta has rush hour every day. Atlanta traffic is always bad.

It appears to be about 20 miles. Would 2 hours be enough do you think?

Also I will be doing Holiday World on Monday 5th June. Any idea what the queues are likely to be on that Monday?

Any tips for getting lots of rides on the day? Do they have a 'fast pass' system? I know they are hated by most people but when you can only get to a park once or twice in your lifetime they are a blessing.
