We are considering a trip to Rarotonga and Aitutaki in Cook Is but also wondering about the outer islands of Fiji. We've been to Fiji but only Coral Coast. I'm just wondering if anyone who has been to both places and would suggest one over the other? As in Aitutaki vs Fiji outer islands? I gather that Rarotonga is similar to mainland Fiji? We're interested in the snorkelling mainly I guess. I'd appreciate any advice.
