I can't find campings in dolomites :(

all the campings I looked at required more than 6 days or weren't available for July. I wanted to stay in camping Olympia, camping cortina and camping seiser alm because of the location. does someone know of any camping near these that I can go with in less than 6 days? it's for a tent, not a trailer
