I'm a climbaholic but hanging out by the beach, soaking in the views seems less intense.
I mean, if you were willing to lug all the crap (portable bike, Camelback, camera, etc.), you might as well have opted to install a motor for bailout situations.
That's my advice for next trip, install a bottom bracket motor for special situations. Then you can sip on your Corona or whatever you were drinking and climb at the same time.
