May can be perfect or it can be scorching hot. As a broad generality, there are probably higher concentrations of single on 1-2 pitch routes in your range on the south facing walls of the Valley and what MP calls Lower Merced Canyon, than on the opposite side of the Valley. Basic tips on how to get the most of a few days there might include; borrowing a Valley guidebook from someone to help you get physically oriented, keeping your eyes open for poison oak in the lower Valley so you don't ruin your trip, realizing that a lot of the Valley routes need two ropes to get down. Pay attention to the lengths of the routes with your 1/2 rope marker. If setting up a toprope on one of these longer routes, remember to tie into the "middle" of the rope rather than the end, so your partner doesn't have to pass the knot. I make these obvious statements because a lot of people climb at places where using one 70 M rope to get down is the standard.
Pat & Jack Pinnacle is very easy to find and has a short approach and has a high concentration of routes you could do. MP has it in Lower Merced - Cascade Falls area - Pat & Jack. The two pitch route Nurdle is a very nice 5.8 from the top of the first pitch you can work your way over (with a little care) to set up top ropes on either Sherries Crack to the left or Knob Job to the right, Both of those harder cracks take excellent gear is you want to lead them after trying on toprope. There are also some very nice sport routes in your grade, like Trough of Justice, Babble oN, Skinheads, Boneheads. A couple of those can take some supplemental gear, read the route notes. On the right side of the cliff there is a nice 5.9 crack, Suds that takes excellent gear. There is a well protected 10a right next to it. IIRC, none of these routes are very steep by Valley standards.
The Church Bowl is another Area that has a bunch of routes concentrated in one place that you could do, and of course Bishop's Terrace should be on everybody's do list. Fantastic route. Black is Brown and Church Bowl Lieback (one of Clint's routes) are both cracks in your range.
Jam Crack route is easy to find and is a great one for your lead list after you get used to Valley Cracks. From the top of the first pitch of Jam Crack, there are two very good 5.10s, Lazy Bum and Bummer, you can TR if you want to get a feel for those grades.
Have a great time in the Valley.
