Here's the map of the closed area at Snow Creek:
https://www.nps.gov/yose/learn/management/closures.htmIf you do end up going to CR, try to stay up at Watkins. It's going to be a short first day if you do (<5 miles). If the little creek below the May Lake>Snow Creek junction is dry, you may just have to go down to Snow Creek. Better yet, since it's so short, just have everyone carry at least 3-4 liters with them right from the trailhead. If there's water in the creek, fine, top off, but you don't have to pump as much, so no big deal. The alternative is a steep descent and a steep climb back up from Snow Creek to Watkins. From Watkins, the second night you'll have to at least get up to Sunrise Lakes (btw- it's Sunrise, not Sunset) or go right and begin making your way to CR, conditions permitting. You'll first get the water you need from the creek you walk over that feeds Pywiack Cascade (look at your map). From there you walk another mile and a half or so to the flat area just before the trail to the summit narrows down and climbs through the manzanita. Go trail right toward the edge of Tenaya Canyon, find a site. If CR is too snowed in to cross over, you turn around, drop down the Forsyth Trail, hit the JMT at a lower altitude and spend the night around the CRxJMT junction. Exit Happy Isles the next day, or, head back up trail just under 2 miles to the junction you passed on the way down and go over toward Merced Lake/Echo Valley, go down the Merced River, spend the next night in the area of the footbridges above Bunnell Cascade, again exit Happy Isles the next day. Other than passing through the Sunrise/CR area,(up and over-ish) you end up with a lower altitude hike that shouldn't be a constant snow-covered navigational challenge or put you into big water crossings.
But, you know, the ranger's suggestion about hiking the North Rim isn't a bad one. If that's something you might be considering, we'll go there when you decide what you want to do.
Being 5'-2", if crossing Tenaya Creek at the Sunrise trailhead is a big deal for you, have one of your taller friends make two trips with their pack and then yours. Bring DEET and a headnet for while you're standing there waiting. If you do get into any snow that lasts, be real, if your compass and route finding skills aren't solid, turn around and save yourselves a lot of grief.
