A hotel in Lignano-Sabbiadoro charges 23,000 euros over the Whitsun weekend. The price does not include breakfast and you have to pay in advance for booking.
Some photos on the booking portal booking.com even show empty returnable bottles. The hotel looks worn out and has apparently not been renovated for a long time. The rooms look dark, especially the bathroom, which is almost completely equipped with dark tiles. The view from the balcony is also not exceptionally beautiful, because the sea is a kilometer away.
