Succulents are also a good choice, they can tolerate quite a long time without water. The advice for them it let the soil dry completely, and then give a complete soak. I have mine in a semi-transparent container with no drain, so I can see the soil get darker, and I know when to stop adding water, and since there is no drain it soaks up the water well (i.e. the sponge hydrophobia the article mentions).
