A dilemma

Both my Christmas cactus are setting buds. They're still out on the deck. I guess they're going to be Thanksgiving cactus this year.

I'm afraid if I bring them inside the buds will drop off. But it's starting to get really cold at night. Heck it's pretty darn cold during the day. I wonder if it's better to bring them inside now while the buds are still small or better to wait until they're bigger and more set?

I have a feeling I'm going to lose the flowers either way and it's probably better to save the plant.
