Gene and Kathy,
My suggestion is to enjoy and embrace the crowds. Strike up conversations when you're waiting at a restaurant. After all, this is Florida's Friendliest Hometown.
Be extra vigilant on the roads. Not only will they be more crowded, but there will be more people who are not familiar and from what I read, get confused on the roundabouts and lost.
We won't be there in February, but hopefully will see you again next time you're down.
Safe travels and have a great time.
