On arriving and eventually finding a place to park at your long term carpark ,I felt that the lighting could have been better .On returning to Luton from our holiday and arriving in baggage collection area I thought the signage for indicating which belt to go to was second to useless .After finding our cases we then went out to find the bus to take us to the carpark .there was already about 25 people with luggage waiting in the pouring rain ,luckily I had an umbrella ,but most of the others just got wet ,little or no protection afforded to the people .We waited nearly half an hour ,and I saw a number of buses,but only one for LONG TERM PARKING which the driver changed his destination on coming round the roundabout to OUT OF SERVICE ,then continued into the pick up area and then out again .When I told the next bus driver of this ,he just said "Oh! he must have been out of his time for driving ".My question is ",do feel that this is a suitable way to treat people.Also my wife hurt her foot walking on the large stones in the carpark.
