As has been said, with 7 day a week availability (as you would in Florida etc), then it is perfectly possible.
I did my PPL in March (2004) in the UK in a month, at an ordinary flying school. I had done all my theory beforehand so could concentrate on the flying. Not boasting, just proof that it can be done if you are available to fly every day in the UK. There are too many who wish to see people rush off the the US.
