could well be our second night away, thank you
@DavidG58 I feel I need to warn you. There IS a barrier ....it isn't particularly hard. From memory you stop at the barrier, read the instructions ( I think they are available in English), you pay by credit card, a ticket is issued, the barrier opens and let's you in.
Your ticket has a number on it, this allows you to get water and also to go in and out ( the number on the ticket opens the barrier too). If you decide to stay more than one night you can simply stroll over put your number in the machine and increase your number of nights. It is very easy .
Of course, this aire may be free at this time of year !
