Note: Depending on your level of desired hospitality, hotel rooms are available on the island in a variety of prices, ranging from ¥300 to ¥1000 per night. On weekends you pay more, up to double the price. By reserving your rooms through online travel sites such as Elong.com you can get confirmed prices much lower than what is commonly listed on other internet information pages. Elong's English site does not have Putuoshan links, but their Chinese site does.
There is one offical page for Hotels:
