Check also that they are happy to carry pax (if this is what you intend). When I hired with an instructor back in Jan 2006 (for a local bimble from Kissemee, FL) they were not pleased with me wanting to bring my wife along. This was because they were treating it as an "air experience flight" (trial lesson) and the insurance wouldn't cover a pax with me sitting left hand seat. When I told them to "forget it then" they made "one last call" to their insurance company who said "okay"!
They didn't want to see my PPL. But I checked the a/c out, did all the flying and told the instructor where we were when he got us lost.
Confirm everything and have a fall back plan. I've hired in the USA, New Zealand and Oz and when you arrive at their office, things are rarely as they appeared when you called / e-mailed the week before.
Have fun though!
