You will find the "Doug's Hawaii" locations to be located basically away from the Hawaii airports. I'm literally along the shore on every location. And this is for a reason, there are actually 3 excellent Hawaiian airport packages and if I jumped into that mix, it wouldn't be pretty, it is confusing enough. So all of the Doug's Hawaii addons are located along the shore, not on land and not near interfering other locations. The only exception to this is the SPB at PHNL. There can be a conflict there depending upon which airport package you are using. But all you need to do is go in and "turn off" the bgl for Doug's Hawaii PHNL SPB (change "bgl" to "off"). Of course the location disappears, but there are many others to enjoy.
I've basically built these for my own pleasure. After all the snow and ice in our "home" area of Alaska, once in a while, I need a palm tree and sunshine! Mostly when I fly there, I fly the Misty Goose and land on the water. All of the locations have piers for water landings (and helipads for the strange fliers that don't use wings!). If I'm in Hawaii and not in the Goose, I'm in a DeltaSim boat going from place to place, just sitting back, watching the water, cool drink in hand, Autopilot heading set and a good book in my lap. There are way points for each location for your GPS. Don't forget to try a nice long boat trip. I've been to many of these ports on a Cruise Ship and have tried to make them as exact as I can based on the real thing.
Because I was enjoying this "Escape from Misty Moorings" so much, I thought it would be fun to share it with anyone else among us that needed a little sunshine. After a lot of work at RTMM, helping build pipelines, dispatches, cabin locations, power plants and whatever, when I feel the burnout coming. I jump in my 787 Dreamliner and take off from Stevens' International at Anchorage PANC and fly direct to PHOG or PHNL (Maui or Honolulu). I play there a couple of weeks, then fly back to Anchorage and go back on the clock.
The "mesh" that is built into Hawaii PhotoReal Plus now is all you need. When the new "Plus" came out, I had to go in and re-do many of the locations because the mesh changed things. I think I've got all of them in good working order as of now. If you are adding new airports, or different meshes, you are beyond my intent for this package, and the risk is yours. I would love to hear your experience, but I won't be spending any time "fixing" it up for future meshes, etc. I'm also purposely not using any of the RTMM team resources ... this is just a personal package from me that I'm sharing with you. It is good medicine for cold weather, then you can Return to Misty Moorings!
