Just some brainstorming on an interesting problem...
-If you can get down in the storm drains in your neighborhood, some of them have VERY large tunnels beneath. Be very careful fucking around in there, but if you have a brain and it's obviously safe you could hang them underground in the cold and dark and dry storm drains, you are just fucked as can be if it rains 1" or more or if it isn't dry in there yet. When it is dry in there, it's like the Sahara. Only drier. If it rained at all you would have to rescue them or lose them.
-If you could find a place to park it in the shade you can rent very large box trucks, you just need a far out of the way place in the shady woods to park it. Set up a small air exchanger system with a hepa filter and you're set. This is a problem that enough duct tape and plastic can solve, and oh how we all love that.
-Forget hotel/motel, that's just fucking stupid. That's like at BEST 1/10 chance you get utterly fucking busted hugely and end up on the news looking like an idiot. Rent a cabin in some out of the way place for a week. Find the best deal closest to you. This is probably what I would do if I had a large amount to deal with. I mean, OUT OF THE WAY. And be so clean and tidy that you can eat the floor. Methodical crazy like.
