We can answer questions better if you give us a some idea what youre looking for. Whats most important to you?
Spectacular diving?
Specific animal encounters?
Pampering and luxury?
Good beginner/intermediate diving?
Opportunities to tour or do other non diving activities?
Avoiding long rough crossings?
Low cost?
