I've been in just your situation; I was bought one of the vouchers for Christmas, and went from Barton, just after I'd got my PPL.
I would go for a location where you are comfortable with the arrangements, so that you are able to concentrate on the differences between Cessna and Tiger Moths!
My recollection was that, in the air, there was not much difference. You will need to wrap up warm, especially if flying in winter.
The P1 was not happy to have me handle the aircraft on the ground, or do the takeoff, due to the tailskid.
I hope you enjoy the experience.
