I have over 400 Aloe plants. A couple of them are Aloe vera. They have to be inside for 5 months of the year due to freezing temperatures. During that time I do not water them. Over the summer, they are outdoors, and get some rain water so I don't water them there. If you grow them in a soil base mix Aloes thrive with a lot of minerals available, and a neutral-alkaline pH), they can easily handle periods of little to no moisture.
I'd say, just give it a good water before you go, and that cloth over the pot is a good idea, to help keep it from drying.
Here's a picture of my largest one (in an 8 gallon pot) from March 5 this year (after 4 months of no water), indoors:
Here's a pic from April 14 (the day it got outdoors):
As you can guess, my point here is that Aloes do not really need as much attention as people assume Especially water-wise, when they're not getting a full day of sun.
