We initially booked this tour for a party of 5, however only 3 of us were able to participate. One due to a sinus infection and the other due to certain prescription medication usage. This was disappointing to us, as had we been made aware of any medication restrictions we may not have booked the tour at all. I recommend that any medication restrictions be clearly advertised in advance. For those of us who did participate in the sea walk, we found it ok, a little murky in the water, but mostly because we were so bummed other members of our party couldn't join. The concept is a cool one. Really put a damper on things.

The experience itself was wonderful. The instructions were clear and concise and they took great care to make sure everything was ok. The actual walk was amazing. Not alot to do on Green Island but worth it to do the helmet dive.

This is great adventure. I really enjoyed it. Although the area is kind of small and time is very short. Staffs are great.
