- Guests who are prone to seasickness or concerned about it are advised to take motion sickness medication in advance, as it will not be available for purchase onboard.
- Since there are no lockers at the activity site and no storage space on the boat, personal items will be locked in the shuttle vehicle during the activity. If this is a concern, please do not book this activity.
The activity only has a simple changing area and shower facilities.
Due to Okinawa's unpredictable weather, sometimes it's only when the boat reaches the Blue Grotto entrance that we learn access inside is impossible. In such cases, the snorkeling activity will be changed to take place in the waters outside the Blue Grotto. If this occurs, no refunds or compensation will be provided.
If the activity is affected by typhoons or bad weather, we will contact you as soon as possible via phone, email, or messaging apps to reschedule or cancel your booking. If you choose to cancel, a full refund will be issued. Please note that due to exchange rate fluctuations, the refunded amount may vary slightly. We appreciate your understanding.
- Minors must submit a paper consent form signed by their parent or guardian upon arrival at the activity venue and must be accompanied by a parent to participate.
No refund or date change will be provided if you are unable to participate in the activity due to personal reasons such as illness or late arrival. Please be advised.
