When they move Bora Bora to Palau, I think you're theory will have some merit. Comparing the low end doesn't shed much light on the issues. While there are the odd few who would sleep in a sleeping bag on the beach because they could do it for free in FP, most aren't interested. Same thing as saying NYC isn't an expensive city , if you qualify your statement by saying the NYC YMCA only charges $12 a night. And I think you're missing point number one that flying to Tahiti is only half way, you've got another leg still to pay for and point number two the cost of travel isn't just the ticket price, true costs are the entire costs of travel including wear and tear and total hours invested waiting for connections, missed pre-paid hotel fees due to connections missed due to multiple individual tickets on multiple airlines...I can assure you I wouldn't be playing the multiple airline game on multiple legs to FP, and in reality nobody else wants to either, that's why FP is considered by travel agents to be the 2nd most expensive destination in the world for vacations. I don't know if Palau is considered a honey moon destination but FP certainly is, as I said FP is a vacation destination not a diving destination. The words French Polynesia and "Once in a lifetime" trip are said in the same sentence often because of the cost, I'm not sure Palau is thought of this way.
But this is to your benefit, go see it now while this is still the case and enjoy the unspoiled, wilderness that FP offers divers who invest the time and money to get there.
I'm not sure I understand your logic. If someone is rich and money is no problem, then they wouldn't care if it cost more to go to French Polynesia vs Palau, they would simply go where the diving is best, period. For the same reason people go to Palau instead of Cozumel.
And now if money is not growing on trees and you are on a budget, my point is simply that French Polynesia does not cost more than Palau. I tried to edit my post because I forgot to insert the cost of the lagoon pass for domestic flights but the site wasn't working earlier today. At 419 euro thats $485 USD so plus $1200 for the flight to HNL/PPT you're still at $1685. You could easily afford a night in HNL going and coming to give you plenty of breathing room on connections and get to visit Honololu for two days and still come in under the cost of a flight to Koror. So the flights cost the same.
I don't suggest anyone sleep in a tent, but at an average $300/night for a couple in a half board pension, I can't imagine it would be that much cheaper in Koror for hotel and meals. And then you're in a not so charming town (Koror) vs living on a beach paradise. And the diving is more expensive on Palau. So why go to Palau? It doesn't save you money, the boat rides are much longer to the dive sites, the dive sites are much more crowded, and the diving appears to be not as good.. so what am I missing?
Seriously, I'm not trying to be argumentative, I'm just trying to understand.
