Is Fiji cheaper than Bora Bora?

I'm curious to know, when it comes to the cost of living and vacationing, is Fiji a more affordable option than Bora Bora? I've heard that both destinations offer stunning natural beauty and unique cultural experiences, but I'm trying to plan a budget-friendly getaway. Could you provide some insights on the relative prices of accommodations, dining, and activities in each location? Are there any significant differences in the cost of flights and transportation as well? I'm eager to make an informed decision and ensure that I can make the most of my travel funds.
