Robthebloke, we have "lower quality" lenses, and CPL and UV to fit them all, so I guess we're set there.

GeoJerry, great advice about not wanting to be overwhelmed with new stuff, and about the exposure issues. I've got a copy of the manual on my iPad and quite a few hours on an airplane to kill, so I'll definatley read up on the things yo mentioned.
We've got a Pentax 18-55, Tamron 18-200, and Quantaray (Tamron) 70-300. I wish we had a 18-135 WR, but I don't think there's time to get one shipped before we leave. I'm thinking the 18-200 will be on the camera most of the time and take the 70-300 for if we need extra reach. The 18-55 will probably stay home. Ideally, I'd like to have a 18-135 WR and also take the 70-300, though.

Just1MoreDave, Yeah, I'm sure we'll be up before dawn early in the stay. I'll bet that first few days back to work are going to be rough, though.
I wish we had some kind of WR lens, but we don't. How water resistant are the Pentax WR lenses, anyway? Some people say "light rain" and some people say they shower the sand off of them. I'm wondering if it would it be worth it to have that 18-135 WR I want shipped out there?
Great shot of the rainbow at the Kilauea lighthouse, too

Brooke Meyer, I plan on shooting RAW+JPEG. Lisa likes to copy the JPEG files to her iPad and send some to family.
Nice shots, too!

Kerrowdown, we definitely want to stay away from Danno!

Thanks everyone for all the great advice!
