Every single time we go on a European sun / beach / villa / complex type holiday, we book it for 14 days and every single time I get to about day 10 and am fed up and want to be at home. I've nothing to complain about except the bed is a bit uncomfortable and I should enjoy my last 3 days of sun and relaxing - but all I can think about is that if I'd bloody remembered and booked 10 days, we'd be flying home tomorrow and I could have had a few days at home in my own bed before going back to work....
I never feel like this on far flung holidays with a packed itinerary etc and holidays are always a few years between so I obviously forget and get all giddy with the booking.....
