A possible alternative is to save up for a few weeks and then have several lessons closer together; you'll have spent less time overall getting back to where you were.
And it can get cheaper after you've got your licence. For example if you rent the same aircraft from the same club the hourly rate for solo hire is probably a little less than for lessons; and you can simply fly less often of course, once every three or four weeks is sufficient to remain current according to many club rules (but not according to the millionaires here who will pop up in a minute and say you're not safe if you're doing less than 200 hours a year). Also there are cheaper aircraft than public CofA trainers.
