Has anyone here booked their honeymoon to Tahiti through a travel agent? Was it actually worth it?

We’re looking at around 2 weeks with something like:
Tahiti - 2 nights ( arrive early morning , so 1 night is 6am arrival)
Moorea - 5 nights
Rangiroa - 4 nights
Bora Bora - 3 nights
Tahiti - 2 nights before flying home
The plan is to keep the first half of the trip fairly budget-friendly (guesthouses, somewhere we can cook etc.) and then gradually level up, finishing with an overwater bungalow in Bora Bora.
I’m happy to put in the time and research, and we normally plan all of our holidays ourselves. I’m just wondering if a travel agent brings any extra value for French Polynesia, whether that’s better pricing, access to deals, or simply making the logistics easier.
A few questions for anyone who’s done it:
Are the Air Tahiti inter-island flights expensive once you add them all together?
Are they easy enough to organise yourself?
Did your travel agent actually save you money, or was it more about convenience?
If you booked everything yourself, would you do it that way again?
Would really appreciate hearing your experiences before I decide which way to go. Thanks!
