Okinawa world

Hi everyone,

I leave Naha in 3 days and still want to do Okinawa World. I would like to have advice on whether to go on Sunday (tomorrow) or on Monday, as well as the hour to start the experience (is 11 am ok? Or earlier is a must?)

Also, as a Pokemon enjoyer, I would like to know about the merch there. The eco bag are limited to 20/day (info found on the website). Should I expect them to be gone early or can I find them at the end of the day too?

Thanks a lot!
