Are guest passes available if you just want to look around

Yes, but you cannot purchase on a visitor pass. You can look and dream. Look for a coupon on the $60 membership fee.

Yes. At the front door just tell them you want to look around, they'll send you to the service desk where they'll give a sort of "day pass". Trust me you'll want a membership after you look around 😉

Yes! Some items can be purchased also at a 10% extra on the guest pass.

I don't think so
