PPR hotel is very nice. It's the most upscale of the hotels in Palau.
The 1hr. ride through the Rock Islands every day is beautiful if you don't mind long rides to dive. The dive op right at the hotel (Splash?) is very good. The boats are comfortable and fast.
As far as the diving, it ranges from no current to speak of to ripping at places like the famous Blue Corner. Don't be too worried, the DM's will supply reef hooks if needed and drop you in up current from the site. They keep the group together and motion for you to hook in where they want you. Then they inflate a marker on a reel and bring everybody up together where the boat picks you right up.
The alternate would be to do a liveaboard. It would be my preference after having been there. The island is beautiful and quiet, but not much to do there. You'll get a better range of diving from liveaboard.
If you have an Ikelite housing I found that by moving the assignment of the white balance "button" into reach of the arm is the ticket. You can organize your personal menu any way you want. The adjustment is somewhere under menu function. Just get the book out (I don't have mine in front of me).
OOPS... I spoke too soon.... Yes this is a problem. While I can get into the white balance menu, I can't reach the one touch white balance command.
I've had a USD Matrix go bonkers. It said deco very shortly into the first dive of the day on the descent. A battery change didn't help this one. I retired it. Luckily I had a back up computer in my pocket that was working fine. I always dive with 2 computers on major trips. I've seen too much of this stuff happen too many times.
