I think you'll have to be careful moving them in and out and vice versa. I don't think they like being moved around, hence the coming inside (or in Shady's garage) and making a mess (they pout). You don't want to stress them more by moving them around repeatedly.
You know how some plants kind of throw a mini-fit after you bring them home from the nursery? Some plants are more "fit throwers" than others. They've went from that "perfect" humidity, light, etc to a spot that has less than perfection so to speak. So, they throw a fit. Some plants adjust after they throw a fit, but if you were to move them again, they might throw another fit. It's not such the big deal moving them outside (as outside has more humidity generally), but bringing them back in.
I just mean you don't want to add anymore stress to them than they already sound like they're in. I am not good with fussy plants so I don't bother attempting to grow these. I know if I did, they'd be outside for as long as they could and it'd be either in the garage or house during the winter. It sounds like you have to nurse them along the best you can while they're inside for the winter though....
I hope this helps.
