Not for Condos, we are full timers and just haven't rented any.
As for areas FL is packed with condos, mostly on the coasts. The farther south you go the more expensive they get with the peak down in the Keys. Especially in January which is right in the middle of 'the season' which runs from Thanksgiving to April depending on the weather up north.
We have stayed in AZ around Benson last winter but don't know much about condos. For winter I'd guess you'll find them around Tucson and maybe Phoenix.
Besides be extremely expensive CA is choked with rules, laws and regs. I'm not sure if most businesses are open. We avoid the place if possible.
