Hi Peter, having just recently returned from the Mono Cr. environs, and with an athletic, first timer, I can contribute something too. I concur with almost everything WD has said, with the exception being that I have always held the diverse forest of Mono Creek in high regard as a thing in itself. She's right that you won't see much above it, but you'll find Red Fir trees with over 4' diameters, and really stately groves of Jeffrey Pines along the trail. I too thought Hopkins Basin was less scenic than all the others, at least until the very top. On our trip up 2nd Recess, near the elevation of the first small lake, we went too high up the left side of Mills Creek, and ran into difficulties. WD also points out trail finding issues in there. It's at least 5+ miles to the beautiful upper lakes, so that makes for a long day trip. Pioneer would be great if you had time to stay overnight up there, and then make the day hike to the ridge for the truly amazing view into colorful McGee Creek. For a day trip though, Laurel Creek would be my rec. too.
Re. the first time backpacker issue, I wouldn't worry too much either, although Manu did have to be coached on toilet routines. When I mentioned smooth stones and snow balls, water, etc... rather than TP, he understood. Bidets are more common in Argentina than here, but he did ask the awkward question of crapping near the creeks, and cleaning up in "el bidet grande, y natural".... shudder. But his fitness made our rough route easily manageable. Manu is a long-time lifeguard, rugby player, and surfer), and he didn't suffer from the trail, only from not drinking enough. *Note that event from our recent TR (see pg 1) :

I hope the trip is a smashing success, good luck, Ian.
