When we plan our trips and secure an RV park, we print the receipt/itinerary and put it in a folder with the dates printed boldly on top. If we plan several trips at one time we then put the first stop on the top. When we are going to the next campground we move the old one to the bottom and the new one on top. When you stop to register you have all your information at hand. At the end of the year, we put all these itineraries in a folder with the year written on it.
It is a great way to keep records of where you have been. If you decide to return to the same campground you can see if there had been a price increase plus you have phone numbers available.
This makes registration quick and easy. Hope this tip has helped you.
