The beginning of February can be nice as far as crowds go but the weather can at times be a little cool. I believe the cheerleaders and band competitions are at that time as well and if I remember the last time we went in early Feb. we had the South American groups as well. I always go the last week of February (last 9 years). Highs in low to mid 80's and very little chance of rain. A little bit more crowded that early February but stil better than holidays or summer.
