I can see trying to work station from a beach chair out on some isolated section of beach. It sounds like the full 100 watts is important, it is only ~3000 miles to the main land. ;-)

Problem with the beach chair setup is power and antenna. That's why a car or SUV or something is better: It can provide both power and antenna, and you can still be at the beach.
Do a google. There's a fella in Brazil who has a web page with lots of magnetic loops he's made, I would think he knows about loops, he's probably very loopy !

I don't have any experience with loops other than the Delta or HO VHF variety so I can't answer you there. I use a rotatable folded dipole atop a 35' piece of bamboo (yeah it grows to giant sizes over here!) for 20 meters and I love it---really quiet and tunes flat across the band.
If I were you (and assuming you'll have a bit of time to get out and operate) I'd build an inverted Vee with ropes on either end (and one attached to the center) ahead of time. When you get to Hawaii, drive somewhere where you find a quiet spot with some trees by a beach and toss the center rope into the tree, tie off the ends to a couple of lava rocks or whatever---and get on the air. You'll have a blast if the band(s) are open at all (and they are open more often than not, at least to somewhere).
Lots of DXCCs scattered all over the Pacific so if the band is dead to EU or Africa or even the mainland there might be a 5W or VK or T32 or JA or... to work otherwise!
Have fun and hope you work lots of DX when you get here. 10 and 17 are great places to hang out, so is 20m IMO. 73 de Jeff in Volcano, HI BK29

What are the thoughts on mag mounting a screwdirver on the rental? I am thinking when I get back I can move that to a hitch mount on my truck. Maybe, I am a bit worried about having a big Steal Me sign on my car at home as well I live in a bad section of town.
A screwdriver on a mag mount is something you could only use when "parked," as if you tried to drive with that on the roof it would fall off. Also the mag mounts don't couple all that well at HF and you might need to add some wire radials to make it effective.
The big (rather huge!) 4-magnet roof mounts that look like a letter "H" with a magnet in each corner are better, and possibly strong enough to drive around (as well as providing more coupling to the roof). If I wanted to use a "mag mount," I'd choose one of those big ones (4-magnet design).
The hitch mount is an invitation for vandalism and also not a great place to mount an HF antenna. "Everything works," but a way better choice is to mount the bottom of the screwdriver up higher, and to do so, most use a welded mount that CANNOT be removed without a cutting torch. You might check K0BG's website for more advice on HF mobile antenna installations.
