It depends on the 7 year old whether it's suitable for him. When we went on this cruise there were young children who seemed to enjoy the experience and handled it well.

It was not an issue to snorkel. The only issue was with scuba diving becuase I had surgery 13 years ago (which has no impact on my diving.) They didn't tell me this was an issue until we were on the boat.

It’s still worth it. It rained on us for a little bit while we were snorkeling at Michaelmas Cay, but 20 minutes later, sun was peaking out. The weather is very fluid there, Hastings Reef was better, but turtles were at the Cay. Since you only have 2 days, you might do Day 1. You might love it so much you go day 2 as well. Also, if you want your picture taken holding a koala bear, go to the Reef Casino in Cairns. They have an option for $25 without having to pay for full Dome experience.

One dive is $55. Two dives is $100 for certified divers.

I’m sure you’d be fine. If you’re heavily pregnant, then maybe avoid the upper deck and the stairs out onto the bow, but there’s a perfectly comfortable lounge/bar area where you’d be ok for sure.

Hi. No. It doesn't.

Definitely the snorkeling and glass bottom boat activities. I am not sure the rules on scuba diving.

Yes - as noted book direct with them - good company
