My advice would be to try to rent an aircraft from the club where you did your PPL - if it's a UK school. It's always difficult to rent an aircraft to take away if the owner doesn't know you or your skills when you are low hours. Make certain you are up to the trip, a PA 28 with full fuel and passengers handles a lot differently than a 150 Cessna if that's what you are used to. Also, passengers can be a big distraction.
