Are you talking about grooming stuff to take? I'd just have the baby brush, a chamois cloth (get it in the car supplies at WalMart), a little cornstarch baby powder - NOT talc.
All you need to do is groom him after you set everything up and then he should be good for the day - maybe a touch up if he's sleeping before the ring call. It will take Godiva longer for her grooming as he's a longhair
Then try to relax tonite - get a good nite's sleep - when you planning on leaving in the morning?
