Does anybody have any opinion on the best place to find affordable vacation packages to Florida or California?

Also, do vacation packages booked on Priceline or other websites actually result in cost savings over booking hotel and air separately?

try aavacations.com, I know sometimes you can pick discount airfare when booking hotel and air.

The answer to your second question is sometimes. If you're looking to save money, you cannot just book a package (from anywhere) and assume it's cheaper than booking separate pieces. If you want it to be easy, packages do provide that.

Where are you looking to travel from for those packages?

I am looking to go to either San Diego or Orlando. Sorry, I should have clarified that earlier.

But where are you traveling from?

Traveling from Chicago.
