Which one would be running week around and would have a fair number of upjumpers at?
There are a couple there at Dillingham, and they usually are flying in the mornings when the tourists are doing tandems. Not many fun jumpers that I know of, and they close around noon or when the tandems are done.

Does any one have any experience how to get to the dz and what places would be cheap and ideal to stay around/at the dz or in Waikiki
The DZ is easy to find on the north shore. If you are going only to jump, just stay on north shore or you'll have a hour or so drive to the DZ from Waikiki, longer if the traffic is bad.
Pacific SKydiving Center was always closing early when I was there, but when they were open I enjoyed the quick flights to altitude on the king air over the slow plane at skydive hawaii...
I did however like Skydive Hawaii's atmoshphere slightly better, and when I was there they did a couple fun jumper only sunset loads two nights a week, those were always a good time...
. The sunset loads would be beautiful, i'm sure.
