I need to make a caramel filling for a cake. I have a bag of caramel bits . I am going to melt it with a little bit of  whipping cream so that it wont be so stiff. Do you guys think it will be ok off of ice for a couple of days?

It will be fine. I make my own caramel filling that has butter, sugar and cream. I don't refrigerate it after and it's fine for a couple days. I think there is so much sugar in it, it sort of preserves it. I wouldn't leave it out for a week, but a few days should be fine.
