I can't recommend Harmony and her crew enough! They were amazing! We were a large group ranging from grandparents in their mid 70's to grandkids 11 and up and every variation of experience level. Between Harmony, Dave, Dillon and Anna, they were able to provide every person with the level of instruction, guidance or freedom that they needed. I felt safe diving with them and my children and they were able to show us all a good time ( and even some SEAHORSES!)
