Hi there, I will be on a Star cruise with my mother who is a senior citizen and will be arriving at Naha Port approximately 12 noon of May 16 2018, and will have about 8 hours to explore Naha. Any suggestion how could we ( with my mother who is at her late 70;s but still great as far as mobility is concerned) be able to see the various attractions at Naha? The cruise has its own excursion package but I wanted to see other options that maybe more economical but worthwhile to enjoy Naha. Any tip and information is highly appreciated. Thank you in advance.
