Setting up a snake before Vacation

[Cam]

Hi All. I will be taking a 2-2.5 week vacation this summer, and the lady who feeds my (other) animals while I'm gone is terrified of snakes. I can possibly get someone else to come by one time but that's a big maybe.

I've got a 5 foot carpet I'll be leaving for that time. I know she won't starve, and her substrate can probably deal with any messes in that time period but I am concerned about her water bowl. I was thinking maybe something similar to the water dish I have for my cats that has a reservoir and tops up the actual "bowl" part continuously, but I'd hate for her to knock it over, or somehow spill a significant amount of water into her cage and be stuck in there with it.

Does anyone have any suggestions?
