I wish I had chosen another day or perhaps another skydive center. Although the experience was amazing (first timer) and I'm looking into skydive training now, I wouldn't recommend that place. I went there because I thought they were the only one on Oahu and this place had been suggested by a friend (who has had a great time there).
I booked online for a Saturday and when my friend and I got there it was crazy, super busy, super loud, very impersonal. We waited 2 h and finally decided to ask when we were going to jump. We had to wait another 2.5 h before getting ready. Had we known, we could have done other things in the meantime. I was supposed to get a photographer for my dive but the (unfortunate) guy had landed badly just before our turn and wasn't able to jump anymore. I finally went for my tandem and the nice guy told me that the photographer had certainly some psychological issues and had been turned down after having asked to do tandems. Very reassuring! Very professional...
Anyway, the skydive experience was great and the tandem guy very friendly, but the structure of the center is messy and not very friendly. I think they should consider their customer like people and not animals and they should tell you when there is a waiting time of 4.5 h so you can go to the beach and come back.
Last but not least, they are very expensive and when you add photos (75$) and video (100$) or both (150$), be ready to tip. They will be very pushy and remind you a great number of times that you're supposed to tip the photo and/or the video guy(s)!
Looking into Pacific for training now.
