We're stopping in a pre-erected tent in Austria for 3 nights in August en route to Italy. Apparently average temps are highs of 22, lows of 10. Will we be warm enough at night in normal sleeping bags or do we need extra blankets? Any ideas re clothing? I don't want to take too much colder weather gear as it's only 3 nights and we've got very limited car space (7 seater car, 6 of us so only half a boot space!)... didn't occur to me before booking or I'd have probably stopped somewhere warmer!
Thanks
