Orchids that can go 2- 3 weeks without water.

[caireparavel]

Over the next year I have to make quite a few trips to Europe , of 2-3 weeks duration.
No problems for all the plants outside , a water timer and the rain Gods will take of them hopefully.

But I got to thinking if I were to start keeping some Orchids inside, are there are any species that anyone knows of that can go 2 weeks plus without water ?

I am unmarried and would trust none of my neighbors with the keys to my house. so any species I wanted to buy to keep inside would have to be able to go through a drought for a while . Thanks
