How much do each person need to pay??

You can purchase a day pass for 49 dollars or you can pay as you go, it's a dollar for each token

You can pay as u go on whatever rides n each rides have different priceing or you can just buy the pass ...im not sure of the pass price.

Depends on how much ride you want to take. A card recharging for 100 dollars gives 140 dollars credits.anyone can use it and has no expiry. They are good enough. Coz noteveryone does everyride. So getting an individual wrist band is not worth.in this 140 credits you are free to.chose and can save money

Depends on how many rides you want to take, in general the wrist band for 4 hours is a better bet to ride unlimited, however it's the same price per person
