Our 7 year old has been taking lots of swimming lessons and is ready to snorkel! Got any suggestions?

Must Haves:
- Excellent house reef for easy snorkeling
- Calm waters and little rain during JUNE/JULY
- Location with no risk of traveler’s diarrhea
- Nothing crazy expensive (North Island, etc). We’re just back from safari!
- Accessible via Star Alliance (No Tahiti )

Nice to Haves:
- Beautiful swimming beach, crystal clear water
- Good kids club

We’ve been looking at FS Hualalai because of King’s Pond.
I’ve been to many spectacular island and diving destinations all over the world but never Hawaii. As an American citizen, that does seem sort of wrong.

Thanks!
