About the vacation thing- What I plan to do once I get some snails (not just a WC slug ) is to take them with me on vacation. It would be easy enough to put them in a big container I have with an inch or two of substrate and just take them, plus that way I could watch them in the car. My family travels in the car most of the time, so no issues with "Excuse me, ma'am, but can your pet stand up and turn around fully in his cage?" "Um...."
That would be very awkward.
