We used to go that week, and it was not warm. I think out of four years going during the first week or two of February, we only swam once, maybe twice. Temps ranged from the low 40's to upper 60's, once or twice hitting the low 70's. We have photo's from 1996 wearing our winter coats/hats/mittens in the parks during the day.
The All Stars and CBR will have cheerleaders, and LOTS of them. We found them VERY Noisy, not always well supervised, and generally a nuisance.
If you are staying at another resort, you will probably not even notice they are there.
As far as Daytona week, there will be a few extra people there, but not enough to make a difference.
