I'll throw this out there...
The Ukumehame firing range on Maui has a range exclusively used by MPD, a 100-yard pistol range used for IPSC and Cowboy Action matches, and a 200-yard range for the general public/non-competitors. That leaves out a precision class, but carbine and/or pistol might be do-able. I believe the range sits empty most of the time since the 200-yard range is usually only open to the public on the 1st Sunday, 2nd Saturday, and 3rd Thursday of the month. Matches at the pistol range are only held on the weekends and MPD has their own range to use. The entire complex is owned by the County of Maui but they farm out the operation of the range to a club called "Valley Isle Sport Shooters". The RO's are all cool if you know what you're doing and follow the rules. I think all of them shoot competitively also. As long as you're safe, 30 round mags, rapid fire, even slide fire stocks are all allowed. So I don't think the idea of having a carbine or pistol class would freak them out.
Having said that, I haven't been there in a long time and don't have any connections with the club so I have no idea if they'd actually allow it.
