My children and I will be traveling to Shanghai Disney for a week in July of 2017.

My question is how would I go about paying for a hotel and the theme park tickets from he U.S. ?
Can I go through the official website and pay with my personal credit card or do I have to take a different method to deal with the exchange rate?
I have not been able to figure it out as of yet.

Thank you,
Shane Sears
