Ideas for a field trip

Hi everyone. We run Goju Ryu karate classes in a couple of schools as well as our own dojo and I would like to pick your brains for field trip ideas to Okinawa.

Let's say we have 4 or 5 days there.

• Where are some good dojos we could maybe take 10 or 15 students of varying ability and ages to train with some Goju Ryu masters (maybe 8th dan or higher, if they will have us)?
• What are some must-see places linked to the history of Goju Ryu you can recommend?
• How about some other fun things? There would likely be some younger kids joining too.

A quick google search showed this camp https://ageshiojapan.com/program/island-karate-camp-in-okinawa, does anyone have experience with them?
