How much does it cost to go to Saipan? How much cash should I bring? How about Hainan Island?

My wife has just been there, and it's about 6000 from Shanghai, but you must remember to live in Saipan when you sign up for a tour! My wife asked them to spend three days in Tianning Island, where only China people run casinos. It's no big deal! Saipan is better in all aspects, and the scenery is the most important thing for tourism! Things on the island are not cheap either. There are duty-free shops, but it is said that they are not as good as Hong Kong and other places. Take 1000 is enough, if it's just for fun. If you bring an international credit card, the overdraft will generally be overdue, because the feedback information may not be timely. Remember to bring your driver's license. You can rent a car locally for $25. This kind of road trip is very interesting. But insurance needs to be considered, 15 dollars. If you don't buy it, you will be in big trouble!
