I'm back in Okinawa and was looking through a travel guide that was published in 2005. It says that there are only two hostels in the main city of Naha at 1500 and 3000 yen per dorm bed.
It is very outdated information. There are many hostels in Naha ranging from 1000 to 1800 yen per dorm bed. Even now, none of the English-language booking engines have complete information on hostels here. I doubt that there were only 2 hostels in Naha back in 2005.
Better information can be found on Web sites by using a search engine. User-generated-content (UGC) means that the online travel Web sites have thousands of "travel writers" in the field continually updating content.
I saw that even Lonely Planet has started offering digital versions of their travel guides – maybe a way to keep the guides updated better?
Is there a future for printed travel guides?
