1-3 day's to optimistic, but they are awesome!

1-3 days is not realistic, these will hold for 1 day, I don't mind and still love them! But I wouldve taken more with me to add a new one if I knew in advance they werent strong enough to really hold more then 1 day. (For 3 people it didnt stay longer then a day, so it was not just a one person thing.)
