The outward journey was excellent, dropping the car off at your Heathrow facility and getting to Heathrow terminal 2 within 20 minutes. The return was another matter. We waited for 20 minutes at the terminal 2 bus stop before a Purple Parking bus turned up. It then did 3 more airport terminal stops picking up and dropping off passengers before getting to the Purple Parking facility on the Bath road some 35 minutes after we boarded. Total time from our arrival at the courtesy bus stop at terminal 2 to driving away in our car was approximately 1 hour - not the nicest way to end a long day travelling.
