I don't have any experiences in growing plants in winters, as I live in tropical country. But I did have some experiences in handling/watering dormant cactus and succulents. Instead of focus on the hot and cold weather, I would rather focus on whether the plants are active growing or whether they are absorbing water or not. Maybe they are highly related, but I just look at them from different angle.
If the plants are having new growth, then I will water more in terms of volume and frequency. Usually we water the C&S more or less all at the same time, I will check on them the next day or two, to know which plants have absorb all the water and which pots are still very wet. For me that is the indication to know who is sleeping, sometimes if they are too wet then I will repot them with new media to prevent rot.
While you bring your plant inside and providing them with GL, I assume you want them to continue growing. I will give them a small amount of water and see if they take it. If they drink and continue to grow, then we can still water them, maybe half or 1/4 of the normal volume, if they don't take the water and went dormant, then we have to stop watering or even unpot the plant to prevent rotting. For me the decision is not on whether we should water or how much water, but more on whether the plants need the water or not.
