I am going to observe here that it sounds as if sunnypie12 has booked already, so warnings to put off what most divers see as the dive of a lifetime until more experienced, are a bit of a waste.
I can think of only 1 dive site we visited in Raja Ampat where I think more experience should be required, and that was a site called Manta Ridge, where in some of the currents you could get into serious trouble if you made a mistake.
We saw some divers there from another option, who required 1 on 1 help from their guides, to keep them safe. That was scary to watch.
In my opinion, every other site we visited was pretty easy diving, even if there were currents.
Just make sure you are quite honest with the dive operation about your level of experience, so they can give you a bit of extra training, and help you gain experience before doing one of the more difficult sites
RA was a wonderful experience for all of us. Fantastic diving, extreme beauty both above and below the water!
Enjoy.
