Very early planning for a trip from UK to hike first 7 days of the John Muir Trail. First thoughts are to fly into San Fran, spend a night then use train/bus via Merced to get to Yosemite. Would return to San Fran for 3 or 4 days afterwards. Problem is where to store non hiking luggage whilst we are on the trail part of our trip, would a decent hotel hold our luggage from the first night until we returned? or are there luggage storage facilities anywhere-even at Merced, have checked the net but struggling to come up with anything! Many thanks!
