The park is super smooth doubt his board will get any damage. This is one of my favorite parks. It's big enough that it never really feels cramped. The park has a great variety of obstacle and transitions to fit any age or style of skating. Amazing pools. Great staff and skateshop. Never heard a real skater complain about his graphic getting scratched. It's supposed to evolve as your skating does. I say take turns with the board you got. Or go old school and buy rails for your board there!! (There is a small entry fee, waiver to sign and they got all the protectors and helmets there as well for sale or rent)
I sorta kinda get that and that's why it's better to buy 2 of the decks so you can hang one up and shred the other. On that note, like buddy said definitely call ahead to make sure they have any available. Keep in mind the rental is not set up to your friends liking or what he's used too as well, if he's a beginner he's going to have a very tough time adjusting to the set up. Tell him to pick up a cheap blank or a plus shop board for 40 bucks and he can turn his current deck into a wall hanger.
That is ridiculous, but I think like $6 if they charge you. But you might want to call because I think they might only have one or two.
