Itinerary question - first time FP

Hi everyone,

My name is Angelo and i'm from The Netherlands. Me and my girlfriend are planning à trip to FP.
Today we booked our tickets and we wil arrive on the 9th of May. Our flight back is on the 30st of May. This means we have 18 nights on FP.

Because it is pretty expensive to visit FB from the netherlands we want to get as much from this trip as we can.
We plan to visit several Islands and atoll's and need some help with the itinerary.
- Arrival Tahiti ( one night)-
- 4 nights Moorea ( pensioen les tipaniers)-
- 3 nights Maupiti-
- 2-3 nights Bora Bora-
- 3 nights rangirao-
- 3 nights tikehau-
- last night on Tahiti

Our intention for this holiday is, relaxing, enjoying the Islands views and an occasional dive.Please comment and suggest. I you have tips on guesthouses please feel free to mention them. We have forecasted about 100 euro's per night for the both of us (cheaper is better Hahaha)

Thanks in advance. 

Small edit:We have 20 nights instead of 18, so we have some more time to spend. 

Camping Chez Nelson on Moorea is a good budget place.....they have basic cabin with two beds at 2500fr a night per person or nicer rooms for more. Bus will drop you off there. Stores about 100meters down the road. Beautiful beach and sunsets. On Bora Bora there are dorm beds for the same price at Stelios pension. You need to phone him to pick you up...no buses on Bora Bora. Ph31 24 94. On the other hand you might prefer some place a bit more romantic and nicer ....maybe a Pension at Matira Point where the only really nice beach is on the main island. Most of the tourists stay at their hotels out on the reef islands and you hardly know they are even there.
